ISIS claims responsibility for Brussels attack that killed 31

Bombs exploded at the Brussels airport and one of the city’s metro stations Tuesday, killing at least 31 people and wounding dozens, as a European capital was again locked down amid heightened security threats. The Islamic State group claimed responsibility for the attacks. The two airport blasts, at least one of them blamed on a suicide bomber, left behind a chaotic scene of splattered blood in the departure lounge as windows were blown out, ceilings collapsed and travellers streamed out of the smoky building. About an hour later, another bomb exploded on a rush-hour subway train near the European Union headquarters. Terrified passengers had to evacuate through darkened tunnels to safety.
