A series of climate protests are continuing in central London for a third night, with police saying 340 people have been arrested in recent days.
Demonstrators have been taking part in 'Extinction Rebellion', aiming to 'shut down' the UK capital.
Protests have been held throughout parts of the city since Monday.
During today's demonstrations, several demonstrators glued themselves to trains, lorries and buildings.
Another group glued themselves together outside the home of Labour leader Jeremy Corbyn in north London.
Those behind the protests are working to highlight the dangers posed by climate change.
They say: "We and our children will face unimaginable horrors as a result of floods, wildfires, extreme weather, crop failures and the inevitable breakdown of society when the pressures are so great. We are unprepared for the danger our future holds.
"The time for denial is over – we know the truth about climate change. It is time to act."

Met Police, who've arrested at least 340 people, have introduced a number of protest restrictions in areas of the city - including Parliament Square, Oxford Circus and Waterloo Bridge.
The force said: "In order to impose this condition, the Met required evidence that serious disruption was being caused to communities in London.
"Based on the information and intelligence available at the time, we are satisfied that this threshold has been met and this course of action is necessary in order to prevent ongoing serious disruption to communities."
Other 'Extinction Rebellion' protests have been taking place in cities such as Berlin and New York.
