A history of recent extremist attacks in Europe

  • Apparently coordinated explosions at the Brussels airport and a metro station killed dozens on Tuesday.

    ISIS has claimed responsibility for the attacks, which happened just days after the top suspect in the recent Paris attacks had been arrested in his hometown of Brussels, after which he told officials he had been planning other attacks from there.

    The attack in Brussels was just the latest in a string of extremist attacks in Europe since the 2004 Madrid train bombings.
