BRUSSELS (Web Desk) – Belgian police have released CCTV footage in an attempt to identify the third attacker at Brussels airport, whose bomb did not explode and who fled the scene.

The man is seen wearing light-coloured clothing and a hat.

Meanwhile, the Belgian Crisis Centre said it had revised the death toll up to 35 after four people died of their injuries in hospital. The attacks were claimed by so-called Islamic State (IS).

The death toll does not include the three attackers.

Investigators have not commented on reports in the Belgian media that the third airport attacker is Faycal Cheffou, a freelance journalist who was arrested last Thursday outside the prosecutor’s office.

Earlier, a man named Faycal C was charged with “participation in the activities of a terrorist group, terrorist murders and attempted terrorist murders,” a prosecutor’s statement said.

Separately, three men were charged on Monday with belonging to a terrorist group.

The three, whose names were given as Yassine A, Mohamed B and Aboubaker O, were arrested during raids on 13 addresses on Sunday. A fourth man was released without charge.

More arrests have also taken place in relation to what authorities say were planned attacks on France.

A man already in Belgian custody was reported to have been charged in connection with a foiled attack in the Paris region.

Separately, Dutch police announced on Sunday evening that they had detained a Frenchman, 32, in Rotterdam at the request of French authorities.

He was arrested on suspicion of preparing an attack in France and will be extradited to the country. Three other people were also detained.

The Frenchman is allegedly linked to Reda Kriket, who was arrested in a Paris suburb on Thursday and said to be in the “advanced stage” of plotting an attack.
