A man known as Faycal C, the only person arrested and charged with involvement in the Brussels attacks, has been released for lack of evidence.

Belgian media gave his name as Faycal Cheffou and said he was suspected of being the mystery third man seen in CCTV footage of the bombers.

Tuesday's attacks on the airport and the city's metro system killed 35 people and injured more than 300.

The attacks were claimed by the Islamic State militant group.

Overnight US Republican presidential front-runner Donald Trump claimed Europe is not safe following recent terrorist attacks.

People on the streets in Brussels have been giving their reaction.
