Priest, 82, and retired teacher, 85, smash case holding copy of Magna Carta in environmental protest

The glass case containing an original copy of the Magna Carta at the British Library in London was smashed by two environmental activists on Friday, causing minor damage to the reinforced box but leaving the historic document unscathed. 

The pair of protesters from Just Stop Oil, a group that has caused widespread disruption in Britain in its campaign to end to the world's reliance on fossil fuels, pounded on the case with a hammer and chisel.

Video footage posted online shows the Rev. Sue Parfitt, 82, and Judy Bruce, an 85-year-old retired biology teacher, holding up a sign reading "The government is breaking the law," before gluing themselves to the display.
