Israel hits Rafah despite US warning on arms transfers

Smoke rose from strikes on Gaza's crowded southern city of Rafah on Thursday after US President Joe Biden vowed to stop supplying artillery shells and other weapons to Israel if a full-scale assault goes ahead.

It was the starkest warning yet from the United States, Israel's main military provider, over the civilian impact of its war against Hamas.

An AFP correspondent and witnesses on Thursday reported Israeli strikes on several parts of Rafah, where the United Nations said 1.4 million people were sheltering.

"The tanks and jets are striking," Tarek Bahlul said on a deserted Rafah street. "Every minute you hear a rocket and you don't know where it will land."

Israel has already defied international objections by sending in tanks and conducting what it called "targeted raids" in eastern Rafah, the city it says is home to Hamas's last remaining battalions.

In an interview with CNN on Wednesday, Biden warned he would stop some US weapons supplies to Israel if it carried out its long-threatened Rafah assault.

Israel on Thursday called Biden's comments "very disappointing".

Biden told CNN: "If they go into Rafah, I'm not supplying the weapons that have been used... to deal with the cities."

"We're not gonna supply the weapons and the artillery shells that have been used."

The fresh warning came after his administration paused delivery last week of 1,800 2,000-pound (907-kilo) bombs and 1,700 500-pound bombs as Israel appeared ready to attack Rafah.

"Civilians have been killed in Gaza as a consequence of those bombs," Biden said. "It's just wrong."

Ties between the allies have become increasingly strained as Biden and other top Washington officials criticise Israel over its conduct of the war.

Pro-Palestinian protests have flared at universities across the United States with an intensity not seen for decades.

The United Nations agency for Palestinian refugees, UNRWA, said 80,000 people have fled Rafah since Monday, but "nowhere is safe".

On Tuesday, Israel seized Rafah's border crossing into Egypt, which had been the main entry point for aid.

The White House condemned the aid disruption, and the defence secretary later confirmed Washington had paused the bomb shipment.

In Israel's first reaction to Biden's threat, its UN ambassador Gilad Erdan called it a "very disappointing statement".

"If Israel is restricted from entering an area as important and central as Rafah where there are thousands of terrorists, hostages and leaders of Hamas, how exactly are we supposed to achieve our goals?" he said on public radio.

Israel's military said on Wednesday it was reopening another aid crossing into Gaza, Kerem Shalom, as well as the Erez crossing into north Gaza.

But it was unclear if aid was entering the territory where, according to the World Food Programme's chief, famine has already begun.

UNRWA said the Kerem Shalom crossing -- which Israel shut after a rocket attack killed four soldiers on Sunday -- remained closed.

Late Wednesday, the army said a soldier was lightly wounded when rockets again targeted Kerem Shalom.

The Hamas authorities' "emergency committee" in Rafah said on Thursday Israel's "control of the Rafah crossing and its closure, along with the halt of aid and fuel supplies, threatens to exacerbate the humanitarian, environmental and health catastrophe".

It dismissed as "nothing but lies" Israel's description of its Rafah operation as "limited".

A US container ship loaded with aid for Gaza left Cyprus on Thursday in a new test of a maritime corridor to get relief into the besieged Palestinian territory, the Cyprus government said.
