UK's Cameron describes 'tough but necessary' conversation with Israel's Gantz

British foreign minister David Cameron said he had spoken with Israel war cabinet member Benny Gantz on Wednesday about Israel's duty to provide aid to Gaza and Britain's concern at the prospect of a military offensive in Rafah.

"I made clear the steps Israel must take to increase aid into Gaza, and the UK's deep concern about the prospect of a military offensive in Rafah," Cameron said. "These are tough but necessary conversations."

On Tuesday, Cameron said he would tell Gantz that patience was running thin over the "dreadful suffering" in Gaza.
