Rubio arrives in Israel as strikes intensify on northern Gaza region

US Secretary of State Marco Rubio arrived in Israel on Sunday, as Israel intensified its attacks against northern Gaza, flattening another high-rise building and killing at least 12 Palestinians.

Rubio said ahead of the trip that he will be seeking answers from Israeli officials about how they see the way forward in Gaza following Israel's attack on Hamas operatives in Qatar last week that upended efforts to broker an end to the conflict.

His two-day visit is also a show of support for the increasingly isolated Israel, as the United Nations holds what is expected to be a contentious debate on commitment to the creation of a Palestinian state. Israeli Prime Minister Benjamin Netanyahu strongly opposes the recognition of a Palestinian state.

Rubio's visit went ahead despite President Donald Trump's anger at Netanyahu over the Israeli strike against Hamas leaders in Doha, which he said the United States was not notified of beforehand.

On Friday, Rubio and Trump met with Qatar's prime minister to discuss the fallout from the Israeli operation. The dual, back-to-back meetings with Israel and Qatar illustrate how the Trump administration is trying to balance relations between key Middle East allies despite the attack's widespread international condemnation.

The Doha attack also appears to have ended attempts to secure an Israel-Hamas ceasefire and the release of hostages ahead of the upcoming UN General Assembly session, at which the Gaza war is expected to be a primary focus.

On Sunday, at least 13 Palestinians were killed and dozens were wounded in multiple Israeli strikes across Gaza, according to local hospitals.

Local hospitals said Israeli strikes targeted a vehicle near Shifa hospital and a roundabout in Gaza City, and a tent in the city of Deir al-Balah that killed at least six members of the same family.

Two parents, their three children and the children's aunt were killed in that strike, according to the Al-Aqsa hospital. The family was from the northern town of Beit Hanoun and arrived in Deir al-Balah last week after fleeing their shelter in Gaza City.

The Israeli military did not have an immediate comment on the strikes.

As part of its expanding operation in Gaza City, the Israeli military destroyed a high-rise residential building on Sunday morning, less than an hour after an evacuation order posted online by the military spokesman Avichay Adraee.

Residents said the Kauther tower in the Rimal neighbourhood was flattened to the ground. There were no immediate reports of casualties.

This is part of the genocidal measures the (Israeli) occupation is carrying out in Gaza City, said Abed Ismail, a Gaza City resident. They want to turn the whole city into rubble, and force the transfer and another Nakba.

Israel strongly denies accusations of genocide in Gaza.

Separately, two Palestinian adults died of causes related to malnutrition and starvation in the Gaza Strip over the last 24 hours, the territory's health ministry reported on Sunday.

That has brought the death toll from malnutrition-related causes to 277 since late June, when the ministry started to count fatalities among this age category, while another 145 children died of malnutrition-related causes since the start of the war in October 2023, the ministry said. The war in Gaza began when Hamas-led militants stormed into southern Israel on October 7, 2023, abducting 251 people and killing some 1,200, mostly civilians. There are still 48 hostages remaining in Gaza, of whom 20 Israel believes are still alive.

Israel's retaliatory offensive has killed at least 64,803 Palestinians, according to Gaza's Health Ministry, which does not say how many were civilians or combatants. It says around half of those killed were women and children. Large parts of major cities have been completely destroyed, and around 90 per cent of some 2 million Palestinians have been displaced.
