Pro-Palestinian activists under the banner of Palestine Action have been waging what it’s not too much of an exaggeration to call a war against companies and institutions in this country that are seen to support Israel’s offensive in Gaza. In one attack last summer at a Bristol facility owned by the British subsidiary of the Israeli defence company Elbit, a van was used to smash through fencing before activists laid about the building with sledgehammers, and two police officers and a security guard were injured in the ruckus.
