Officers at Midi train station after bomb attacks in Brussels on Tuesday. Reuters A third bomb, which failed to explode during Tuesday's attacks at Brussels Airport, was safely deactivated, a spokeswoman said.

The terrorist group ISIS, also known as the Islamic State, ISIL, or Daesh, has claimed responsibility for the coordinated assault on Belgium's capital that killed at least 30 people.

Two explosions shook the airport, while another hit a metro station.

The attacks followed the arrest of Salah Abdeslam, a suspect in last year's attacks on Paris, who was detained last week after a police raid in a Brussels neighborhood.

The head of Brussels Airport said the airport would remain closed at least through Wednesday.
