A manhunt has been launched for one of the terrorists behind coordinated bombings in Brussels which left 34 dead and almost 200 injured.
As a series of police raids were mounted across Belgium, prosecutor Eric van der Sypt said two suicide bombers died in the attack on the main airport in Brussels and a third was being "actively" sought.
Belgian police issued an image of the man, one of three seen pushing luggage trolleys through Zaventem airport moments before two bombs exploded.
A third bomb was deactivated at the airport hours after the attack.
In a statement, Belgian police appealed for information about the man, who is wearing a hat and a light-coloured jacket.
"Police are looking to identify this man. He is suspected of having committed the attack at Zaventem on Tuesday March 22," it said.
"If you recognise this individual or have information regarding this attack please call 0800 30 300."
The airport attack was followed by a bomb blast on a Metro train in the city centre as terrorists inflicted a new outrage on a European capital.
