The UK government has suspended 30 arms export licenses to Israel over fears that the British-made arms could have been used in violation of international humanitarian law.
The suspension, announced by foreign minister David Lammy on Monday, came after a review over the summer over the UK's exports to Israel.
The suspension comes after a day of general strike action called on Sunday by Israel's Histadrut labour federation, in a bid to pressure the government of Prime Minister Benjamin Netanyahu to reach a ceasefire deal and exchange of captives.
The strike, which has seen thousands of people take to the streets to block roads on Sunday night and Monday, came after the Israeli army found six captives dead in a tunnel in Gaza.
As pressure mounts against Netanyahu in Israel, the military has continued carrying out its bombardment across Gaza where four people were killed in a strike on a house in the Bureij Refugee Camp, according to the Palestinian news agency Wafa.
Bombing struck other areas of Gaza including Khan Younis and the Nuseirat Refugee Camp, while strikes on Gaza City killed five people.
Israel's war on Gaza, which has been ongoing for 11 months, has killed 40,738 people and wounded a further 94,154.
