Over 30 persons were killed and several others injured due to three explosions at the Brussels airport and the Metro Station, reports said.

Two blasts were earlier reported in the departure hall of Zaventem airport in Brussels.

Brussels airport has suspended all operations until further notice.

The blasts have been reported four days after the arrest in Brussels of Salah Abdeslam, the prime suspect in the November terrorist attacks on Paris that killed 130 people. Belgian police had been on alert for any reprisal action.
