Climate campaigners Just Stop Oil have sprayed universities across England with orange paint.
Protests were reported on Thursday at the universities of Leeds, Manchester and Cambridge.
Just Stop Oil say the protests are "against the UK Government's plans to license new oil and gas projects".
It follows protests at Bristol on Monday, Exeter and Oxford on Tuesday and Falmouth, Sussex, Birmingham and UCL on Wednesday.
Last month the Rosebank oil field, the UK's largest untapped oil field estimated to contain up to 300 million barrels of oil, was given the go-ahead by regulators.
The activist group posted a video on X, formerly known as Twitter, of the University of Leeds' Great Hall being "redecorated orange", saying the person featured in the clip was recent Leeds graduate Sam Holland.
In the video, Mr Holland appears to be spraying orange paint on the building and shouting the university is "complicit in genocide" through its graduate schemes. He is then dragged away by police.
