All hostages are now reportedly safe following an incident in the northern French town of Roubaix near the Belgian border.
Police sources said that the incident appeared to be robbery-related and was not thought to be linked to the Paris terror attacks on 13 November.
"This is apparently not a terrorist attack, it's apparently a robbery," one police source said.
Reuters initially reported several people suffered gunshot wounds during the incident.
A source said:
An operation is underway after hostages were taken.
Gunshots were fired and the neighbourhood has been cordoned off.
A bank director and his family may have been taken as hostages.
Medical and fire services confirmed that an operation was underway in the town, but haven't given further details.
