Six people have been arrested after a campaign group targeted fuel terminals in a protest against oil.
The arrests were made at three sites in Thurrock, Essex Police said.
Oil company Exxon Mobil has temporarily suspended operations at three other terminals due to a series of co-ordinated “small protests”.
Campaign group Just Stop Oil said it had blocked 10 “critical” sites including in Birmingham, Hemel Hempstead and Hythe in Kent.
Operations from these locations had been halted, Exxon Mobil said.
Just Stop Oil said in a statement: “The Just Stop Oil coalition is demanding an end to the government’s genocidal policy of expanding UK oil and gas production and is calling on all those outraged at the prospect of climate collapse and suffering from the cost-of-living crisis to stand with us.
“Ordinary people can no longer afford oil and gas, it’s time to just stop oil.”
