Speaking to Trevor Phillips on Sky News, Lord Cameron said an arms embargo would strengthen Hamas and make a hostage deal less likely.
An Israeli arms embargo is “not a wise path” and the UK and America are “in a totally different situation”, the foreign secretary has said.
Lord Cameron told the Sunday Morning With Trevor Phillips Show that it would be “extremely dangerous” for Israel to attempt a major offensive in Rafah.
But asked if the UK would follow in the US’s footsteps and halt the supply of weapons to Israel if launches an attack on the southernmost city of Gaza – a crucial route for aid – he said the UK and America “are in a totally different situation”.
“The United States is a massive bulk state supplier of weapons to Israel, including, you know, 1,000lb pound bombs and all the rest of it,” he said.
“The UK provides less than 1% of Israel’s weapons and is not a state supplier. We have a licensing system and those licences can be closed if it’s judged there’s a serious risk of a serious international human rights violation.”
He added that when he last came under pressure to announce an arms embargo, “a few days later there was a massive Iranian attack on Israel, including 140 cruise missiles.
“So I don’t think it would have been a wise path.”
“If I announced that today, it might help me get through this television interview, but actually it would strengthen Hamas. It would weaken Israel,” Lord Cameron said.
“I think it probably makes a hostage deal less likely. So I don’t think some sort of political declaration is the right answer. We should stick with our rigorous process of making sure we act within the law.”
Israel has called on residents of Rafah in Gaza to evacuate and head to the “expanded humanitarian area” as it prepares to ramp up its military assault.
Despite heavy US pressure, Israel has said it will proceed with an assault on the southern city, where more than 1.4 million people have taken refuge from the fighting – around half of them children.
Israeli forces say Hamas militants are dug in, so Rafah is key to its goal of dismantling the group’s capabilities and returning scores of hostages captured in the 7 October attack by insurgents that triggered the war.
But tensions over the gathering offensive have led Joe Biden to warn the US would stop supplying Israel with some weapons if it presses ahead with an invasion.
UK ‘should pause weapons to Israel’
Labour said a full-scale offensive into Rafah would be “catastrophic beyond description” and the UK should adopt the US’s position.
Shadow frontbencher Jonathan Ashworth told Sky News. “We do not want to see weapons used in Rafah and like Joe Biden has said, if that goes ahead those weapons should be halted and we believe the government should adopt that position now.”
