Gaza residents will be provided with tents and other shelter equipment Sunday ahead of relocating them from combat zones to the south "to ensure their safety," the Israeli military said on Saturday.

This comes days after Israel said it intended to launch a new offensive to seize control of northern Gaza City, the enclave's largest urban centre, in a plan that raised international alarm over the fate of the demolished strip, home to about 2.2 million people.

Israeli Prime Minister Benjamin Netanyahu last Sunday said that before launching the offensive, the civilian population will be evacuated to what he described as "safe zones" from Gaza City, which he called Hamas' last stronghold.

The shelter equipment will be transferred via the Kerem Shalom crossing in southern Gaza by the United Nations and other international relief organizations after being inspected by defence ministry personnel, the military said.

A spokesperson for the United Nations Office for the Co-ordination of Humanitarian Affairs expressed concern over Israel's plans to relocate people to southern Gaza saying it would only increase suffering.

But the UN body welcomed Israel's recognition that shelter is a desperate need and that tents and other shelter equipment will be allowed again into Gaza. "The UN and its partners will seize the opportunity this opens," the spokesperson said.

The UN warned on Thursday that thousands of families already enduring appalling humanitarian conditions could be pushed over the edge if the Gaza City plan moves ahead.

Palestinian and United Nations officials have said no place in the enclave is safe, including areas in southern Gaza where Israel has been ordering residents to move to.

The military declined to comment when asked whether the shelter equipment was intended for Gaza City's population estimated at around one million people presently, and whether the site to which they will be relocated in southern Gaza would be the area of Rafah, which borders Egypt.

Israel's Defence Minister Israel Katz said on Saturday that the plans for the new offensive were still being formulated.

The Palestinian militant faction Islamic Jihad, an ally of Hamas, said that the military's announcement "as part of its brutal attack to occupy Gaza City, is a blatant and brazen mockery of international conventions."

However, Israeli forces have already increased operations on the outskirts of Gaza City over the past week. Residents in the neighbourhoods of Zeitoun and Shejaia have reported heavy Israeli aerial and tank fire.

Residents there have also reported explosions throughout the day, resulting from Israeli tank shelling against homes in the eastern parts of the neighbourhood.

The Israeli military on Friday said that it had begun a new operation in Zeitoun to locate explosives, destroy tunnels and kill militants in the area.

Ceasefire negotiations stalled
The war began when Hamas attacked southern Israel on October 7, 2023, killing 1,200 people and taking 251 hostages, according to Israeli authorities, and 20 of the remaining 50 hostages in Gaza are still alive.

Israel's subsequent military assault against Hamas has killed over 61,000 Palestinians, Gaza's health ministry says. It has also caused a hunger crisis, internally displaced most of Gaza's population and left much of the enclave in ruins.

Protests calling for a hostage release and an end to the war were expected throughout Israel on Sunday, with many businesses, municipalities and universities saying they will support employees striking for the day.

Negotiations to secure a U.S.-backed 60-day ceasefire and hostage release ended in deadlock last month, and mediators Egypt and Qatar have been trying to revive them.
