On the morning of 22 March 2016, three coordinated nail bombings occurred in Belgium: two at Brussels Airport in Zaventem, and one at Maalbeek metro station in Brussels. In these attacks, 32 victims and three perpetrators were killed, and over 300 people were injured. Another bomb was found during a search of the airport. Islamic State of Iraq and the Levant (ISIL) claimed responsibility for the attacks.

The bombings were the deadliest act of terrorism in Belgium’s history. The Belgian government declared three days of national mourning.


Belgium is a participant in the ongoing military intervention against ISIL, during the Iraqi Civil War. On 5 October 2014, a Belgian F-16 dropped its first bomb on an ISIL target, east of Baghdad. On 12 November 2015, Iraq warned members of the coalition that Abu Bakr al-Baghdadi, the leader of ISIL, had ordered retaliatory attacks on countries involved in the coalition against ISIL.

Belgium has more nationals fighting for jihadist forces as a proportion of its population than any other Western European country, with an estimated 440 Belgians having left for Syria and Iraq as of January 2015. Due to Belgium’s weak security apparatus and competing intelligence agencies, it has become a hub of jihadist-recruiting and terrorist activity.

– Terrorist cells in Brussels

Before the bombings, several Islamist terrorist attacks had originated from Belgium, and a number of counter-terrorist operations had been carried out there. In May 2014, a gunman with ties to the Syrian Civil War attacked the Jewish Museum of Belgium in Brussels, killing four people. In January 2015, anti-terrorist operations against a group thought to be planning a second Charlie Hebdo shooting had included raids in Brussels and Zaventem. The operation resulted in the deaths of two suspects. In August 2015, a suspected terrorist shot and stabbed passengers aboard a high-speed train on its way from Amsterdam to Paris via Brussels, before he was subdued by passengers.

The perpetrators involved in the November 2015 attacks in Paris were based in Molenbeek, and Brussels was locked down for five days to allow the police to search for suspects. On 18 March 2016, Salah Abdeslam, a suspected accomplice in those attacks, was captured after two anti-terrorist raids in Molenbeek that killed another suspect and injured two others. At least one other suspect remains at large. During interrogation, Abdeslam was presented with photographs of the Bakraoui siblings, who would later be suspected of committing the attacks in Brussels three days later. Belgian investigators believe that Abdeslam’s arrest may have hastened the Brussels bombings. According to the Belgian Interior Minister, Jan Jambon, who spoke after the bombings, authorities knew of preparations for an extremist act in Europe, but they underestimated the scale of the attack.


There were three coordinated attacks: two nail bombings at Brussels Airport, and one bombing at Maalbeek metro station.

– Brussels Airport

Two suicide bombers, carrying explosives in large suitcases, attacked a departure hall at Brussels Airport in Zaventem. The first explosion occurred at 7:58 a.m. in check-in row 11; the second explosion occurred about nine seconds later in check-in row 2. The suicide bombers were visible in CCTV footage. Some witnesses said that before the first explosion occurred, shots were fired and there were yells in Arabic. However, authorities have stated afterwards that no shots were fired.

A third suicide bomber was prevented from detonating his own bomb by the force of a previous explosion. The third bomb was found in a search of the airport and was later destroyed by a controlled explosion. Belgium’s federal prosecutor confirmed that the suicide bombers had detonated nail bombs.

– Maalbeek metro station

Another explosion took place just over an hour later in the middle carriage of a three-carriage train at Maalbeek metro station, located near the European Commission headquarters in the centre of Brussels, 10 kilometres (6 mi) from Brussels Airport. The explosion occurred at 09:11 CET.

The train was travelling on line 5 towards the city centre, and was pulling out of the Maalbeek station when the bomb exploded. The driver immediately stopped the train and helped to evacuate the passengers. The Brussels Metro was subsequently shut down at 09:27.

– Profiles

A total of five attackers were involved, with three of them dying in suicide bombings and the remaining two arrested in the weeks after. All had involvement in the planning and organization of the November 2015 Paris attacks. They were identified and named as:

  • Ibrahim El Bakraoui: aged 29. Died in a suicide bombing at Brussels Airport. In 2010, he had been involved in an attempted robbery at a currency exchange office and a subsequent shootout with police that left one officer injured. He was sentenced to 10 years in prison but was paroled in 2014 under the condition that he did not leave the country; he was sought by authorities when he violated those conditions.

  • Najim Laachraoui: aged 24. Died in a suicide bombing at Brussels Airport alongside Ibrahim El Bakraoui. He reportedly travelled to Syria in 2013 and, under a false identity, became a prison guard for ISIL until 2014, after which he returned to Belgium. At the time of the bombings, he was suspected of involvement with a possible terrorist cell and was awaiting trial.

  • Mohamed Abrini: born 27 December 1984. Abrini assisted Ibrahim El Bakraoui and Najim Laachraoui in the airport bombings. He was a childhood friend of brothers Salah Abdeslam and Brahim Adbeslam, who were both involved in the November 2015 attacks in Paris, and is suspected of assisting Salah Abdeslam in his escape following the attacks. He is also suspected of having fought for the Islamic State in Syria.

  • Khalid El Bakraoui: aged 27, and the younger brother of Ibrahim El Bakraoui. Khalid El Bakraoui died in a suicide bombing at the Maalbeek metro station. In 2011, he was convicted for several carjackings, the possession of a number of Kalashnikov rifles, and a 2009 bank robbery and kidnapping. After being released in 2015, El Bakraoui failed his parole appointments and abandoned his address. He was later served with three arrest warrants, one from Interpol, one international, and one European.

  • Osama Krayem: born 1992. Krayem assisted Khalid El Bakraoui in the suicide bombing at the metro station. When he was eleven, he participated in a Swedish documentary film about the integration of migrants into Swedish society. Krayem is believed to have been radicalized by videos of Anwar al-Awlaki, and that he had been fighting for ISIL since 2014. Before the bombings, he was one of Europe’s most wanted fugitives.

In security camera video of Brussels Airport, Ibrahim El Bakraoui, Laachraoui, and Abrini were seen pushing suitcases believed to have contained the bombs that exploded in the departure hall. A taxi driver who drove them to the airport said he tried to help the men with their luggage but they ordered him away. Initial reports elaborated El Bakraoui and Laachraoui each apparently wearing a glove which may have concealed detonators to the explosives. This was later proven to be untrue, with both being barehanded.

– Investigation

Within 90 minutes of the airport attack, the area around an apartment in Schaerbeek, a northern district of Brussels, was cordoned off by police. The authorities received a tip-off from a taxi driver once they released photos of the suspects several hours after the attacks. Inside the home, they discovered a nail bomb, 15 kilograms (33 lb) of acetone peroxide, 151 litres (33 imp gal; 40 US gal) of acetone, nearly 30 litres (7 imp gal; 8 US gal) of hydrogen peroxide, other ingredients for explosives, and an ISIL flag. At least one resident reported unusual smells to the police, resulting in Agent de Quartier policeman Philippe Swinnen visiting the building twice in three months, but not entering.

Authorities also found a laptop belonging to Ibrahim El Bakraoui, inside a waste container near the house. The laptop had a suicide note stored on it, in which Ibrahim stated that he was “stressed out”, felt unsafe, and was “afraid of ever-lasting eternity”. It also contained images of the home and the office of the Belgian Prime Minister, Charles Michel, among information on multiple other locations in Brussels.

Numerous related arrests followed after the bombings. As of 26 March, twelve men were arrested in connection with the bombings.


Raids and searches were made across Belgium, while security was heightened in a number of countries as a result of the attacks.

– Belgium

Authorities temporarily halted air traffic to the airport and evacuated the terminal buildings. The airport was to be closed to passenger traffic and reopening date postponed several times with a projected reopening date of 29 March. The Berlaymont building, which is near Maalbeek station and is the headquarters of the European Commission, was placed in lockdown. Controlled explosions were carried out on suspicious objects around Maalbeek station.

All public transport in the capital was shut down as a result of the attacks. Brussels-North, Brussels-Central, and Brussels-South stations were evacuated and closed, and Eurostar journeys to Brussels Midi station were cancelled. All trains from Paris to Brussels were also cancelled. Taxis in Brussels transported passengers free-of-charge for the duration of the lockdown. Paris Nord railway station, with services to Brussels, was also temporarily closed.

The Belgian Interior Ministry raised the terror alert level in the country to the highest level following the attacks. The government warned that some perpetrators might still be at large and urged citizens to reach friends and family using social media to avoid congesting the telephone networks.

The country’s two nuclear power plants – Tihange and Doel – were partially evacuated as a precaution.

Temporary border checks were implemented by Belgian and French authorities at some major crossings on the France-Belgium border.

The federal government announced three days of national mourning, lasting from Tuesday until Thursday, and flags were flown at half-mast on public buildings. They also held a one-minute silence at noon local time on 23 March.

Also on 23 March, Belgian Muslim groups, such as the League of Imams in Belgium and Executive of the Muslims in Belgium, publicly condemned the bombings and expressed their condolences to the victims and their families.

The airport was closed on 22 March, with reopening postponed several times. On 29 March, an operational test was performed. The official reopening date was scheduled to be announced on 30 March. A post-reopening target of 800–1,000 passengers per hour was projected, compared to pre-bombing traffic of 5,000 passengers per hour. The delay in the reopening was attributed to extensive damage to the building’s infrastructure. A temporary terminal is planned for use after the reopening. When the airport reopens, only Brussels Airlines will serve the airport, but other airlines will be allowed to return later.

On 29 March, it was revealed that Ibrahim and Khalid El Bakraoui were released from prison due to a law introduced in 1888 known as Lejeune, which allows inmates to be released after serving a third of their sentence. Belgian Interior Minister Jan Jambon stated that the governing parties had agreed to update the law in 2014. The Lejeune law first came under scrutiny after serial killer and child molester Marc Dutroux was released from prison in 1992.

Airport businesses were affected. Hotel closures included the Sheraton Brussels Airport Hotel and Four Points by Sheraton Brussels.[90] Cargo flights resumed on 23 March. Car rental offices were also closed.

Following memorials to the victims, disturbances broke out, resulting in riot police using water cannons to disperse violent right-wing protesters against ISIL.

On 30 March, plans to reopen the airport were cancelled again due to a strike by airport police over a dispute over inadequate security. The dispute was resolved, and the airport was later scheduled to be reopened on 3 April. On that day, a Brussels Airlines flight left for Faro and a flight to Athens and Turin was scheduled for the same day. Upon reopening, only passengers were allowed to enter a temporary departure hall and security checkpoints were implemented at the roadway to the airport. Only car and taxi traffic were allowed to enter but public transit remains suspended. Hotel business revenue in Brussels had been cut in half since the airport closure.

On 1 April, religious leaders in Brussels gathered together for a memorial to the victims of the bombings. They expressed their desire to spread a religious message of unity throughout Belgium, and to combat extremism.

On 25 April, the Maalbeek metro station reopened with heightened security. On 1 May, the departure hall of Brussels Airport, which had sustained the most damage during the bombings, partially reopened with the airport on high alert.

– Other countries

Soon after news of the attacks broke, security was increased, particularly at airports, railway stations and other transport hubs, in China, Denmark, France, Germany, Greece, Indonesia, Ireland, Italy, Japan, Malaysia, Malta, the Netherlands, the Philippines, Thailand, the United Kingdom, and the United States. Also, Portugal evacuated the check-in section for 20 minutes due to a suspicious abandoned bag. In addition, Israel stopped flights from Europe for the rest of the day; additional police were deployed to the Belgian border with the Netherlands; the United Kingdom’s Foreign and Commonwealth Office said the Belgian authorities were advising against non-essential travel to Brussels; and officials at the U.S. Embassy in Brussels warned of the possibility of more attacks, recommending “sheltering in place and avoiding all public transportation”.


In a televised address to the nation on 22 March, King Philippe expressed his and the Queen’s sorrow at the events. His Majesty offered their full support to members of the emergency and security services.

Following the bombings, several structures around the world were illuminated in the colours of the Belgian flag, including the Brandenburg Gate in Berlin, the Eiffel Tower in Paris, the Trevi Fountain in Rome, the National Gallery in London’s Trafalgar Square, and the Burj Khalifa in Dubai. New York Governor Andrew Cuomo announced that One World Trade Center, the tallest skyscraper in the Western Hemisphere, would be illuminated in the flag’s colours on the night of the attacks, while the spire of the Empire State Building went dark. The Toronto Sign was lit up in the colours of the Belgian flag on the night of the attacks.
