Extinction Rebellion protesters glue themselves to research centre supported by Cambridge University

Extinction Rebellion climate activists glued themselves to the building of an oilfield services giant, calling on the University of Cambridge to cut ties with the firm.

Protesters arrived early on Friday to attach themselves with glue to the main entrance of Schlumberger's research facility in Cambridge.

Schlumberger - also known as SLB - is a global company that provides technology and infrastructure for oil and gas extraction, to firms including BP and Shell.

A number of people dressed as climate scientists, wearing white lab coats and handing leaflets to staff members as they entered the building.
