Israeli strikes on the southern Gaza city of Rafah overnight killed 13 people, including nine children, health officials said on Sunday, as the United States was on track to approve billions of dollars in additional military aid for its close ally.

Israel has carried out near-daily air raids on Rafah, where more than half of Gaza’s population of 2.3 million have sought refuge from fighting elsewhere.

It has also vowed to expand its ground offensive to the city on the border with Egypt despite international calls for restraint, including from the US.

The House of Representatives approved a 26 billion dollar (£21 billion) aid package on Saturday which includes around 9 billion dollars (£7.3 billion) in humanitarian assistance for Gaza.

The first overnight strike killed a man, his wife and their three-year-old child, according to the nearby Kuwaiti Hospital, which received the bodies. The woman was pregnant, and the doctors managed to save the baby, the hospital said.

The second strike killed eight children and two women, all from the same family, according to hospital records. An air strike in Rafah the night before killed nine people, including six children.

The Israel-Hamas war has killed more than 34,000 Palestinians, according to local health officials, devastated Gaza’s two largest cities and left a swathe of destruction across the territory.

Around 80% of the population have fled their homes to other parts of the besieged coastal enclave, which experts say is on the brink of famine.

The conflict, now in its seventh month, has sparked regional unrest, pitting Israel and the US against Iran and allied militant groups across the Middle East. Israel and Iran traded fire directly earlier this month, raising fears of all-out war between the long-time foes.

Tensions have also surged in the Israeli-occupied West Bank.

The Israeli military said troops “neutralised” two Palestinians who attacked a checkpoint with a knife and a gun near the southern West Bank town of Hebron early on Sunday. It was not immediately clear if they were killed. No Israeli forces were wounded.

At least 469 Palestinians have been killed by Israeli soldiers and settlers in the West Bank since the start of the war in Gaza, according to the Palestinian Health Ministry.

Most have been killed during Israeli military arrest raids, which often trigger gunbattles, or in violent protests.

The war in Gaza was sparked by an unprecedented raid into southern Israel on October 7 last year, in which Hamas and other militants killed around 1,200 people, mostly civilians, and abducted around 250 hostages.

Israel says militants are still holding around 100 hostages and the remains of more than 30 others.

Thousands of Israelis have taken to the streets to call for new elections to replace Prime Minister Benjamin Netanyahu and a deal with Hamas to release the hostages.

Mr Netanyahu has vowed to continue the war until Hamas is destroyed and all the hostages are returned.

The war has killed at least 34,049 Palestinians and wounded another 76,901, according to the Gaza Health Ministry.

The ministry does not differentiate between combatants and civilians in its count but says at least two-thirds have been children and women.

It also says the real toll is likely to be higher because many bodies are underneath the rubble left by air strikes or are in areas that are unreachable for medics.

Israel blames Hamas for civilian casualties because the militants fight in dense, residential neighbourhoods, but the military rarely comments on individual strikes, which often kill women and children.

The military says it has killed more than 13,000 Hamas fighters, without providing evidence.
