Several people have been killed and many were injured after a suspected terrorist attack at Brussels Airport this morning. Hospital sources say that 10 have been killed, according to a report by Guardian.

According to French media reports, there were two explosions minutes apart just before 8 a.m. at Brussels airport – one in the departures area and one on or near the runway, writes Angelique Chrisafis. Ceiling broke down spreading dust and smoke.

“The departures area had easy access to the public, but the runway area would have been closed to public access and raises questions about how the explosion could have happened there.”

Here is the first video which appeared about the attack.

The entire metro system of Brussels has been closed.

Belgium Prime Minister Charles Michel said his government is monitoring the situation minute-by-minute. In a tweet he said the “top priority” was the victims of the blasts.

Two loud explosions took place shaking the building. Terrified passengers fled for their lives. This happened around 8 a.m. local time, Mirror reports.

The airport has been “locked down,” the flights have been canceled and all traffic towards Belgian airport has been suspended.

One of the travellers tweeted, “We are being evacuated from the back of the Metro, between Schuman and Maelbeek.“Smoke in the tunnel as we evacuate.”

“Pictures from the airport showed bloodied victims, shattered glass and debris as well as smoke pouring from the terminal and passengers fleeing with their bags,” reported NBC.

“There was an explosion … there are several dead and wounded but we can’t say how many at this point,” a federal police spokesperson said.

“Soon after that one a second one hit — and everything came down. There was dust everywhere, glass everywhere there was chaos. There were people on the floor everywhere. The roofing came down. It was quite a mess,” one of the eye witnesses said.
