At least 26 people have been killed in violence around Paris and hostages have been taken at a theatre in the French capital.
Officials said shots were fired in at least two restaurants and at least two explosions were heard near the Stade de France stadium, where the national side was playing Germany in a friendly football match.
French president Francois Hollande left the stadium, where he had been watching the game, to hold an emergency meeting.
Prime Minister David Cameron said: "I am shocked by events in Paris tonight. Our thoughts and prayers are with the French people. We will do whatever we can to help."
