RAFAH, Gaza Strip — Israel’s defense minister laid out his vision Thursday for the next phase of the war in Gaza, describing how Israeli forces would shift to an apparently scaled-down “new combat approach” in northern Gaza, while continuing to fight Hamas in the south of the territory “for as long as necessary.”

Ahead of a visit by the U.S. secretary of state, Yoav Gallant also outlined a proposal for how Gaza would be run once Hamas is defeated, with Israel keeping security control while an undefined, Israeli-guided Palestinian body runs day-to-day administration, and the U.S. and other countries oversee rebuilding.

Israel has come under heavy international pressure to spell out a postwar vision but so far has not done so. The issue is likely to be on the agenda in Secretary of State Antony Blinken’s talks this weekend in Israel and other countries in the region. The United States has pressed Israel to shift to lower-intensity military operations in Gaza that more precisely target Hamas, after nearly three devastating months of bombardment and ground assaults.

The vagueness of many of Gallant’s provisions made it difficult to assess how much they mesh with the U.S. calls.

The document issued by Gallant was titled a “vision for Phase 3” of the war, and Gallant’s office said the phase had not yet begun. It also said the ideas were Gallant’s and not official policy, which would have to be set by Israel’s war and security cabinets.

Gallant, who is a member of both cabinets, may be aiming to put his personal plan before the Americans ahead of others in Prime Minister Benjamin Netanyahu’s coalition, which includes hard-right members likely to want a tougher approach.

Much of northern Gaza, which troops invaded two months ago, has been flattened beyond recognition. With the focus now in the south, Israeli forces are battling Hamas militants in the city of Khan Younis and in urban refugee camps in the center of the territory.

More than 85% of Gaza’s 2.3 million people have been driven from their homes and squeezed into smaller slivers of the territory. Israel’s siege of the territory has caused a humanitarian crisis, with a quarter of the population starving because not enough supplies are entering, according to the U.N.

At the same time, airstrikes and shelling across Gaza continue to destroy houses, burying families taking shelter inside.

An Israeli strike Thursday flattened a home in Mawasi, a small rural strip on Gaza’s southern coastline that Israel’s military had declared a safe zone. The blast killed at least 12 people, Palestinian hospital officials said: a man and his wife, seven of their children and three other children ranging in age from 5 to 14, according to a list of the dead who arrived at Nasser Hospital in nearby Khan Younis.

There was no immediate response from Israel’s military.

Gallant’s statement underlined that the war would go on until Hamas’ military and government capabilities are eliminated and the more than 100 hostages still in captivity are returned.

In the north, the statement said, forces will shift to a new approach that includes raids, destruction of tunnels, “air and ground activities and special operations.” The aim would be “the erosion” of the remaining Hamas presence.

There was no word whether northern Gaza’s population, which has almost entirely been driven south, would be allowed to return.

The statement did not clarify how the new approach would differ from current operations, but Gallant previously said it would be a lower scale.

In the south, he said, fighting would continue “as long as is deemed necessary.”

After the war, the statement said, Israel would keep security control, taking military action in Gaza when necessary to ensure that there are no threats and maintaining inspections of all goods entering the territory.

Gallant said there would be no Israeli civilians in Gaza, ruling out calls by some in Israel’s far-right for a return of Jewish settlers to the territory.

Palestinian entities — apparently local civil servants or communal leaders— would run the territory, with Israel providing “information to guide civilian operations,” the statement said without elaborating. A multinational task force, led by the U.S., would be in charge of rebuilding.

The apparent picture of an Israeli-dominated Palestinian administration for Gaza differs starkly from U.S. calls for a revitalized Palestinian Authority to take control of the territory and a start to new negotiations toward creating a Palestinian state alongside Israel. Netanyahu and other Israeli officials have rejected that idea.
