Hundreds of campaigners across the UK have gathered outside several defence factories to protest against arms being sent to Israel.
Workers for a Free Palestine, a campaign group, said it had blockaded sites in Bournemouth, Glasgow, Brighton and Lancashire, some of which are operated by defence giant BAE Systems.
Demonstrators want BAE systems and other companies to cut ties with Israel and stop supplying it with any weapons.

They also want the UK Government to back a permanent ceasefire in Gaza and are calling for Israel to leave the Occupied Palestinian Territories.
Many of the BAE factories targeted on Thursday are said to be involved in the supply of parts for F-35 fighter aircraft, which the group says is being used in Israel’s bombardment of Gaza.
Jenny, a spokeswoman for the Workers for a Free Palestine group, who did not give her surname, said: “The fighter jets these factories help to produce are being used to imprison the people of Gaza in a death trap.
“They are ordered to evacuate when they have nowhere safe to go, while our government still refuses to back a ceasefire.
