Protesters have locked themselves together and set off red smoke flares after throwing paint outside the offices of a defence company in London.

Two campaigners from Palestine Action attached themselves to each other using lock-on devices, outside French weapons maker Thales’ London headquarters on Thursday morning, preventing all access to the Quadrant.

The premises were also drenched with red paint using repurposed fire extinguishers, symbolising the bloodshed of the Palestinian people.
