The sound of an explosion has been recorded at a football match between France and Germany at the Stade de France.

France has declared a national state of emergency and has closed its borders after dozens of people were killed in multiple shootings in Paris.

At least 80 people are reported to have been killed at the Bataclan arts centre, where gunmen held a number of people hostage.

Three people were killed in a separate attack at the Stade de France, a senior football official said.
