Paris attacks: Belgium charges fourth suspect with role

Belgian police have charged a fourth suspect with terrorism offences related in the deadly attacks on Paris, the federal prosecutor has said.

The unnamed man was one of 16 people arrested in raids on Sunday. The rest have been released without charge.

Belgian PM Charles Michel said he would maintain the highest security threat level in Brussels, warning of an imminent threat.

But authorities plan to reopen schools and the metro on Wednesday.

The co-ordinated assaults in Paris - claimed by so-called Islamic State (IS) - left 130 people dead.

A statement from the federal prosecutor's office said the man had been charged with "participating in activities of a terrorist group and with [a] terrorist attack".

Of a further five people arrested on Monday morning, two have been released while "further enquiries" are under way regarding the others, the prosecutor said.

Mohammed Amri, 27, and Hamza Attou, 20, have already been charge with aiding Paris attacks suspect Salah Abdeslam, who remains at large. A third, unnamed suspect has also been charged.
