The prayer hall in Lagny-sur-Marne, around 30 kilometres (18 miles) east of the capital, was shut down last Wednesday following a large-scale police operation.

The locations of the raids were not given.
A revolver and jihadist documents were also found during searches at the homes of the mosque leaders, Interior Minister Bernard Cazeneuve said previously.
A total of 22 travel bans and nine house arrests for "radicalised individuals" have been issued as a result of the operation.
