LONDON (Reuters) - Demonstrators from the Extinction Rebellion group, which is demanding urgent action by governments and business to limit climate change, staged a sit-down protest that stopped traffic from using Tower Bridge in London on Monday.

A Reuters photographer saw around 200 protesters taking part in the demonstration at the north end of the bridge while groups of police officers tried to prevent others from joining.
