Several people have been injured and hundreds are trapped after two explosions rocked Brussels Airport.
Witnesses said they ‘felt the shockwaves’ of the blast which are believed to have centred on the American Airlines check-in desk at 8am (7am GMT).
Pictures show the terminal windows blown in from the force of the explosion and smoke rising high into the sky.
The incident came as the Belgian capital was on a state of high alert following the arrest of Paris terror attack suspect Salah Abdeslam in the city last week.
Flights are being suspended with aircraft diverting to nearby airports.
At least 13 people have died and up to 50 injured after two explosions rocked Brussels Airport in a suspected suicide bombing.
There were reports that shouts in Arabic were heard before the explosions and shots fired in the aftermath.
Around 90 minutes later, there were reports of another suspected terror attack after explosion hit a Metro station near the EU headquarters in the city centre.
Photographs from inside the arrivals hall showed the floor was covered in fallen roof tiles and dust as bloodied people hobbled out of the airport. Others injured were photographed lying on the floor.
The explosions come just a day after the Belgium Interior Minister warned of possible revenge attacks after the arrest of Paris massacre suspect Salah Abdeslam in the city last week.
