Salah Abdeslam had been planning more attacks from Brussels and potentially had access to weapons, according to Belgium's foreign minister.

Abdeslam claimed "he was ready to restart something from Brussels, and it's maybe the reality," Didier Reynders said on Sunday afternoon.

"We found a lot of weapons, heavy weapons in the first investigations, and we have seen a new network of people around him in Brussels," he added.

Abdeslam has been charged with "terrroist murder" since his arrest by Belgian authorities on Saturday.
