Two Just Stop Oil protesters in their 80s have smashed the glass around the Magna Carta at the British Library.
Reverend Sue Parfitt, 82, and Judy Bruce, 85, a retired biology teacher, targeted the protective enclosure around the historic document with a hammer and chisel on Friday morning.
A statement from the British Library said its security team “intervened to prevent further damage to the case, which was minimal” and “the Magna Carta itself remains undamaged”.
The gallery that houses the display is closed until further notice, it added.
“We must get things in proportion. The abundance of life on earth, the climate stability that allows civilisation to continue is what must be revered and protected above all else, even above our most precious artefacts.”
Ms Bruce said: “This week 400 respected scientists – contributors to IPCC reports, are saying we are ‘woefully unprepared’ for what’s coming: 2.5 or more degrees of heating above pre industrial levels.
“We must get off our addiction to oil and gas by 2030 – starting now.”
Two people have been arrested on suspicion of criminal damage and are currently in custody, the Metropolitan Police said.
