Just Stop Oil supporters have sprayed orange paint on four buildings in Central London.
They are demanding that the government halts all new oil and gas licences and consents.
At 8:30am today, 6 Just Stop Oil supporters sprayed orange paint from fire extinguishers on the Home Office, the MI5 building, The Bank of England and the headquarters of News Corp at London Bridge.
The buildings were chosen to represent the pillars that support and maintain the power of the fossil fuel economy – government, security, finance and media.
