Flags fly at half-mast on Whitehall government buildings as the United Kingdom observed a minute's silence on Monday 16 November 2015. The minute's silence was held across Europe at 11am (UK time), in remembrance of those who lost their lives in the series of terrorist attacks in Paris, France.
France has declared a national state of emergency and tightened borders after at least 150 people were killed in a night of gun and bomb attacks in Paris. Eighty people were reported killed after gunmen burst into the Bataclan concert hall and took dozens hostage. The siege ended when security forces stormed the building.
