The Belgian capital Brussels was hit by a series of deadly terrorist attacks on Tuesday morning, just over four months since the devastating assault on Paris by jihadists.
On Tuesday afternoon, police released an image of three suspects who were caught on tape by surveillance cameras at Brussels Zeventum international airport prior to the attacks.
The airport was hit by two explosions shortly after 8am, then at around 9.20am there were reports of explosions at at least one Metro station in the city.
At least 31 people (revised down from the earlier death toll of 34) were killed in the blasts according to the latest reports and over 100 more left injured. Later on Tuesday the terror group Isis claimed responsibility for the deadly bombings.
Brussels transport authorities confirmed that at least 20 people died in the blast at Maelbeek Metro station and over 100 injured.
At least 10 were killed in the airport blasts, with over 80 injured.
A third unexploded bomb was later found at the airport in Brussels.
The Belgian prosecutor later confirmed that the airport explosions were suicide bombings, confirming the fears that the capital had been targeted by terrorists.
There were unconfirmed reports of a Kalashnikov being found at the departure lounge at Zeventem airport. Some witnesses had talked of a shooting before the explosion at the airport.
The blasts come just days after the arrest in the city of Salah Absdeslam - the chief suspect from the Paris terror attacks who had been on the run for four months.
Witnesses spoke of panic in the streets as survivors stumbled out of Maelbeek Metro station covered in blood and suffering burns.
The city quickly went into lockdown, with the airport - an international hub serving countries around the world- immediately closing until at least 6am Wednesday and the city's Metro system was evacuated.
The city's museums were also closed and the public transport system suspended. Universities were also evacuated.
There were reports of raids taking place at addresses across the city as Belgian police began the quest to identify the attackers.
Authorities in Paris immediately upped security at the city's airports and reinforced checks. There was also an alert at Gare du Nord station in Paris, where trains depart to Brussels and London.
The bomb squad was sent in but it proved to be a false alarm.
