At least 31 people were killed and 190 wounded when three explosions hit Brussels on Tuesday morning, the first two at Zaventem airport and the third on a subway train near European Union headquarters. Belgian federal prosecutor Frederic Van Leeuw called all three explosions terrorist attacks, and ISIS later claimed responsibility for them, the Associated Press reported. Belgium raised its terror threat to the highest level for “a serious and imminent threat.”

Here are the key details to know:

Three explosions targeted transportation hubs in Brussels

Two blasts hit Brussels airport, around 8 a.m. local time. The first explosion tore through the departure hall, while the second happened minutes later in another area. Images and videos shared on social media showed shattered windows, fallen ceiling tiles and broken glass scattered around the departure hall, while a plume of smoke was also seen rising from the terminal as passengers fled the area. A third bomb was later deactivated at the airport, according to the AP. Belgian Health Minister Maggie de Block said 11 were killed and 81 injured at the airport.

The third blast hit Maelbeek station in the city center, a short walk from many European Union offices, around 9:10 a.m. Brussels Mayor Yvan Majeur told reporters that the bomb on the subway train killed 20 and injured more than 100 people, the AP reported.

ISIS claimed responsibility for the attacks

ISIS claimed responsibility for the attacks on Tuesday. The group said its members opened fire in the airport and said “several” detonated suicide belts, the AP reported. Police said a photo published in Belgian news media shows three men who have been identified as suspects in the bombings, theNew York Times reported. Police posted a cropped version of the photo onFacebook and Twitter, asking for help identifying one of the men.

One suspect thought to have fled the airport is now being sought by police, after the two other men “probably” carried out suicide bombings, according to Belgian prosecutors. Chemical products, an ISIS flag and a new explosive device containing nails were found during raids taking place throughout the country, the AP reported.
