Belgian government confirms there are victims at Brussels #Zaventemairport blast.
The cause of the explosions is unknown. The airport is being evacuated and has been closed to flights.
The blasts come four days after the capture in Brussels of Salah Abdeslam, the main suspect in the jihadist attacks in Paris on 13 November 2015.
Watch video below:
Rail transport to the facility has been halted and people have been told not to come to the airport.
All flights have been diverted.
Other reports say at least one of the explosions was close to the American Airlines check-in area but this has not been confirmed.
The Belgian broadcaster RTBF quoted a witness as saying there were people injured or unconscious in the departure area, opposite the Sheraton hotel.
Niels Caignau, a Swissport employee, told Flemish 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.”
Belgium’s Interior Minister Jan Jambon had said on Monday that the country was on the highest level of alert for possible revenge attacks after the capture of Salah Abdeslam.
He told Belgian radio: “We know that stopping one cell can… push others into action. We are aware of it in this case.”
Zaventem airport is 11km (7 miles) north-east of Brussels and dealt with more than 23 million passengers last year.
