The United States hinted on Friday at disagreement with Israel over how quickly to scale down the war in Gaza, with President Joe Biden’s national security adviser saying such timing was now the subject of “intensive discussion” between the allies.

With intense ground fighting having expanded this month across the length of the Gaza Strip and aid organisations warning of a humanitarian catastrophe, Biden said at the start of the week that Israel risked losing international support because of “indiscriminate” air strikes killing Palestinian civilians.

Biden’s national security adviser, Jake Sullivan, visited Israel on Thursday and Friday, and U.S. officials briefed journalists that he was carrying a message to Israel to scale down the broad military campaign and transition to more narrowly targeted operations against Hamas leaders.

The New York Times quoted four U.S. officials as saying Biden wanted that to happen in around three weeks. But speaking to reporters, Sullivan avoided a direct answer about the timing.

“There will be a transition to another phase of this war, one that is focused more precisely on targeting the leadership and on intelligence-driven operations,” he said.

“When exactly that happens and under exactly what conditions will be a continuing intensive discussion between the United States and Israel,” he said.

“The conditions and the timing for that was a subject of conversation I had with” Prime Minister Benjamin Netanyahu, other Israeli government leaders and military commanders, added Sullivan.

During Sullivan’s visit, Israeli officials publicly emphasised that they would carry on the war until they achieve their stated aim of eradicating Hamas, the group whose fighters rampaged through Israeli towns killing 1,200 people and capturing 240 hostages on Oct. 7

Netanyahu told Sullivan on Thursday Israel would fight “until absolute victory”. Defence Minister Yoav Gallant said the war would “last more than several months”.

Israeli government spokesperson Eylon Levy said Israel was winning the war and degrading Hamas, citing as evidence a reduction in the number of rockets fired into Israel.

But hours later there were sirens in Jerusalem and explosions overhead from at least three interceptions by Israel’s Iron Dome air defences, for the first time in weeks. The armed wing of Hamas claimed responsibility for the rocket attack in response to “Zionist massacres against civilians”.

AID ROUTE OPENED

Sullivan did appear to obtain one major concession from Israel, which announced shortly after he left that it would open the main road link into Gaza for aid shipments for the first time since the war began.

Previously, aid permitted into Gaza has been trucked to Israel’s Kerem Shalom crossing, inspected there, and then trucked back into Egypt to enter through the Egyptian-controlled Rafah crossing, designed mainly for pedestrians.

Aid agencies, warning of mass starvation and disease for Gaza’s 2.3 million residents, have long pleaded for Israel to speed up deliveries by letting aid enter directly at Kerem Shalom. The Israeli cabinet said its decision to do so would allow 200 trucks per day into Gaza, compared to a capacity of just 100 at Rafah.

Sullivan said Washington welcomed “this significant step,” which he said he had been informed of before he left.

‘BALL OF FIRE’

Gaza health authorities say close to 19,000 people have been confirmed killed, with thousands more feared buried under rubble.

Gaza residents reported another night of intense fighting and bombardment the length of the enclave on Friday, including in Sheijaia, Sheikh Radwan, Zeitoun, Tuffah, and Beit Hanoun in the north, and in the centre and northern fringes of the main southern city Khan Younis.

Hospitals in Deir al-Balah, Khan Younis and Rafah reported a new influx of dead and wounded early on Friday.

“The Gaza Strip turned into a ball of fire overnight, we could hear explosions and gunshots echoing from all directions,” Ahmed, 45, an electrician and father of six, told Reuters from a shelter in a central area of the densely populated enclave.

“They can destroy homes and roads and kill civilians from the air or through blind tank shelling, but when they come face to face with the resistance, they lose.”

Washington has shielded its long-term ally Israel diplomatically so far, vetoing a U.N. Security Council resolution a week ago calling for a ceasefire, but Biden’s strong remarks on civilian casualties this week were a shift in tone.

The past two weeks have seen an intensification of combat since a week-long truce collapsed at the start of December, with Israel now extending its ground campaign from the northern half of the enclave into the south.

Although Israel had said its forces had largely achieved their objectives in the north, fighting there has only worsened, while also spreading to the south, where most of the population is now sheltering. The vast majority of Gazans have been driven from their homes over the past two months, many several times.

The Israeli military said on Friday that it had mistakenly killed three hostages held in Gaza after wrongly identifying them as a threat during combat in Shejaiya. Earlier on Friday it said it had recovered the bodies of three other hostages killed by Hamas. Israel says it believes around 20 of more than 130 hostages still held in Gaza are dead.

Al Jazeera, the Qatar-based pan-Arab TV channel, one of the few international broadcasters still operating out of Gaza, said one of its cameramen, Samer Abu Daqqa, was killed in an Israeli strike while covering the aftermath of a strike on a school.

The broadcaster’s Gaza correspondent Wael al-Dahdouh was injured. Dahdouh is well known to viewers across the Middle East after learning last month during an emotional live broadcast that his wife, son, daughter and grandson were killed in an Israeli air strike.
