The nation-wide terror alert for Belgium has been risen to level four — its highest — after explosions rocked the airport and one subway station there in the early morning hours Tuesday. Belgium state broadcaster RTBF has reported that the Brussels airport explosion was a suicide bomber.
ABC has reported that at least 28 people have been killed in the attacks.
The blasts come less than a week after Salah Abdeslam, the ringleader of the terrorist attacks in Paris, was captured in a raid in the Molenbeek neighborhood of Brussels.
