Stopping British arms sales to Israel if it launches a ground assault on Rafah in the Gaza Strip would strengthen Hamas, Britain's Foreign Secretary David Cameron said on Sunday.
Israel ordered Palestinians to evacuate more of the southern city on Saturday in an indication it was pressing ahead with its plans for a ground attack, despite U.S. President Joe Biden's threat to withhold the supply of some weapons if it did so.
Cameron said he did not support an operation in Rafah in the absence of a plan to protect hundreds of thousands of civilians sheltering in the southern border city.
However, Britain was in a "completely different position" to the United States in terms of providing arms to Israel, he said, noting that less than 1% of Israel's weapons that came from Britain were already controlled by a strict licensing system.
"We could, if we chose to, make a sort of political message and say we are going to take that political step," he told the BBC's Laura Kuenssberg.
