Police arrested a woman connected to the attacker on Friday, a French prosecutor said.

Lakdim, who was initially believed to have acted alone, held up a car, fired on police and seized hostages in a supermarket on Friday, in what President Emmanuel Macron called an act of "Islamist terrorism".

A gendarme who voluntarily took the place of a hostage during the siege has died, France said earlier today.
