Just Stop Oil (JSO) supporters have been met by angry members of the public as the group launched one of its biggest protests.
Some 160 activists marched in 16 groups across London, according to JSO, which said some were shoved and knocked to the ground, including a visually impaired woman and a young student.
A video posted on Twitter shows members of the public pushing activists, wearing orange high visibility vests and carrying placards, off the road.
