A suicide bomber detonated at the Maalbeek Metro Station in Brussels, Belgium. In addition to the bomber, at least 16 people were killed in the blast. This was one of two coordinated attacks targeting transportation infrastructure in Brussels on the same day. Additionally, at least 270 people were injured across both incidents. The Islamic State of Iraq and the Levant (ISIL) claimed responsibility and stated that the attacks were carried out in retaliation for Belgium’s participation in a coalition against ISIL.
