Dozens of pro-Palestinian protesters have blocked the entrances to a BAE Systems factory in southeast England, targeting Britain’s biggest military supplier to call for an end to arms sales to Israel.

Holding up a sign saying “Stop Arming Israel” and waving Palestinian flags, about 50 people stood in front of one entrance at the Rochester, Kent, site, where BAE tests and assembles electronic equipment used on military aircraft and in surveillance systems.

Tens of protesters gathered at other entrances.

BAE said it does not directly export any equipment to Israel, but the group is a tier-one supplier on the United States-made F-35 fighter jets which are flown by Israel.
