British activists shut down Monday two drone factories owned by Israeli arms company Elbit, as part of a protest called "Block the Factory," marking one year since the Israel's Operation Protective Edge in Gaza.

The two factories are UAV Engines in Shenstone, Staffordshire and Instro Precision in Broadstairs, Kent, the BBC reported. A similar factory was targeted in Melbourne, Australia.

Carrying banners that read "This factory is closed" and "Elbit Drones Murder," the activists scaled the walls and blocked the roads in front of the plants.

London Palestine Action spokeswoman Elly Hassan was quoted in local media as saying that the U.K. "is colluding in Israel's war crimes against the Palestinians" by allowing the factories to maunfacture and sell drone parts.

“Not only has the U.K. government done nothing to stop Israel massacring Palestinians, it actually provides Israel with enormous diplomatic, financial and military support," he said.
