Another Bomb hit Brussels Train Station leaves 20 dead and scores injured

At least 20 people have been killed and 55 are gravely injured after terrorists blew up a crowded Metro train this morning in a second devastating attack on Brussels. Shocking images from Maelbeek station show the mangled remains of the train, smoke pouring out of the building and casualties littered on the pavement outside - just 400metres from the EU's headquarters. Watch video after the cut.

The bomb went off at 9.19am - just over an hour after two explosions killed at least 14 and seriously injured 50 after a suicide attack on the Belgian capital's main airport. 

Brussels’ public transport authority has revealed that the three-carriage train at Maelbeek was ripped apart by a single explosion, with bomb set off in middle carriage. 

Commuters on the Metro at the time described hearing a loud bang before they were evacuated from trains and forced to walk down smoke-filled tunnels and along the track to the closest safe station.
