Two Israeli air strikes targeting aid supplies killed at least 11 Palestinians in Gaza on Monday, medics said, as Israeli tanks pushed deeper into Rafah in the south and fought their way back into areas in the north they had already subdued months ago.

One strike at a food distribution centre in Gaza City, near the Shati historic refugee camp, killed three people. Another, near Bani Suhaila town in the southern Gaza Strip, killed at least eight, including guards who accompany aid trucks, the medics said.

There was no immediate comment from Israel, which denies attacking aid efforts and accuses militants of causing harm to civilians by operating among them.

Overnight, an Israeli air strike at a medical clinic in Gaza City killed the director of Gaza's Ambulance and Emergency Department, the enclave's health ministry said. Israel's military said that strike had killed a senior Hamas armed commander.

The health ministry said the killing of Hani al-Jaafarawi brought the number of medical staff killed by Israeli fire since Oct. 7 to 500. At least 300 others have so far been detained.

In a statement, the Israeli military said the strike targeted Mohammad Salah, who it said was responsible for developing Hamas weaponry.

NO CEASEFIRE ACCORD

More than eight months into the fighting, international mediation backed by the United States has so far failed to bring a ceasefire agreement. Hamas says any agreement must end the war, while Israel says it will agree only temporary pauses in fighting until Hamas is eradicated.

On Monday, Israeli Prime Minister Benjamin Netanyahu said he remained committed to a proposed ceasefire and hostage deal, announced by U.S. President Joe Biden in May.

"We are committed to the Israeli proposal that President Biden welcomed. Our position has not changed. The second thing, which does not contradict the first, we will not end the war until we eliminate Hamas," Netanyahu said in a speech to parliament.

In Rafah, near the border with Egypt, Israeli forces which had taken control of the eastern, southern and central parts of the city pursued their raid into the western and northern areas, said residents, describing heavy fighting.

On Sunday, residents had said Israeli tanks had advanced to the edge of the Mawasi displaced persons' camp in the northwest of Rafah, forcing many families to leave northward to Khan Younis and to Deir Al-Balah in central Gaza, the only city in the enclave where tanks have not yet invaded.

"The situation in Tel Al-Sultan, in western Rafah, remains very dangerous. Drones and Israeli snipers are hunting people who try to check on their houses, and tanks continue to take over areas overseeing Al-Mawasi further west," Bassam, a resident of Rafah, told Reuters via a chat app.

The Israeli military said forces continued "intelligence-based targeted operations" in Rafah, locating weapons and rocket launchers and killing militants "who posed threats to them."

In the north of the enclave, where Israel had said its forces completed operations months ago, residents said tanks had pushed back into Gaza City's Zeitoun suburb and were pounding several areas there.

In Deir al-Balah, now the last refuge for many thousands of Gazans following the assault on Rafah, medics at a clinic were trying to treat malnutrition in children and measure the extent of hunger stalking the Strip.

"With the displacement, communities are settling in new locations that do not have access to clean water, or there is not adequate access to food," said Muaamar Said, a doctor with aid group International Medical Corps. "We fear there are more cases being missed."
