Several people were wounded in a stand-off between police officers and hostage takers in the French town of Roubaix.
Local news outlets reported children were among the hostages at a local gas station. The terrorists are armed with Kalashnikov sub-machine guns. Witnesses reported gunshots being fired. Media reports say the area has been closed off by police.
It is not yet clear whether or not the situation erupted following a series of anti-terrorist raids of Belgian and French police in the aftermath of the Paris attacks.
Senior police officials have said that the situation is not related to terrorism.
