More than 1,000 protesters have descended on central London for a huge demonstration by climate group Extinction Rebellion.
The activists blocked all of the roads around Parliament Square as they planned to bury a coffin which they said represented the future of life on the planet.
Images showed the coffin being marched to Downing Street and the gates of Buckingham Palace during Saturday's rally.
Photos also showed police and protesters clashing. The Met Policelater confirmed 14 arrests had been made, all for criminal damage.
