Another blast has been reported at Brussels' Maalbek metro station less than an hour after two other explosions killed and injured dozens at Brussels' Zaventem airport.
Two loud explosions were reported Monday morning at Brussels airport, with images on social media showing smoke rising from one of the terminal buildings, according to reports from the BBC and other agencies.
The airport blast comes just days after Belgian authorities captured Salah Abdeslam in connection with the November attacks on Paris which killed over 130 people. Described as "the most wanted man in Europe" Brussels has remained on a high alert since his capture. The Belgian foreign minister warned Abdeslam was "trying to restart something" in Belgium.
The cause of the explosions is unknown. French daily Le Figaro has reported 11 people are dead, but casualties are unconfirmed by authorities.
Belgian media have reported the airport is being evacuated, all flights are closed, and rail transport to and from the airport has been halted.
Niels Caignau, an airport employee, told local broadcaster VRT: "I was on a break and heard and felt a big explosion - we have from here a view over the departure hall and saw a plume of smoke come out. The windows are completely shattered. People went outside in shock. It doesn't look good."
The latest blast at Maalbek station occurred at the entrance. Maalbek station is located meters away from a number of important EU buildings in Brussels, including Berlaymont building, which houses the EU Commission and the Council of the European Union.
