Climate activists smash windows at Barclays' London HQ

The seven activists from the Extinction Rebellion group used hammers to break the windows and then pasted the message "In Case of Climate Emergency Break Glass" on the front of the bank's building.

Extinction Rebellion said the action was part of its so called "Money Rebellion" against the capitalist system which used "nonviolent direct action, causing damage to property to prevent and draw attention to greater damage."

Barclays could not be reached for immediate comment.
