Belgium hiked its terror threat to its highest level after deadly explosions at Brussels airport Tuesday, Interior Minister Jan Jambon said.

The alert level was raised from three to a maximum of four, and was applied across the country, Jambon's spokesman said, according to the Belga news agency.

The move was announced after twin blasts hit Brussels' Zaventem airport, killing at least one person, and shortly before staff on the city metro reported an explosion at Maalbeek station, near the European Union's main buildings.
