Israel has imposed new restrictions on aid entering the besieged Gaza Strip and will not open the Rafah crossing as planned, as Israeli forces have killed several people in the Palestinian territories as pressure mounts for a ceasefire with Hamas.

Israel informed the United Nations on Tuesday that it would only allow 300 rescue trucks – half of the number initially agreed – Daily entry into Gaza starting Wednesday.

Olga Cherevko, spokesperson for the United Nations Office for the Coordination of Humanitarian Affairs in Gaza (OCHA), confirmed that the United Nations had received a note from the Organization for the Coordination of Government Activities in the Territory (COGAT), the Israeli military agency responsible for overseeing aid inflows into Gaza.

COGAT’s note said no fuel or gas would be allowed into the war-torn enclave except for special needs related to humanitarian infrastructure.

Al Jazeera’s Hani Mahmoud, reporting from Gaza City, said allowing 300 trucks a day to deliver aid was “far from enough” for famine-stricken Gaza.

“Three hundred is not enough. It’s not going to change anything,” he said.

Israeli authorities also announced that the Rafah crossing between Gaza and Egypt would remain closed.

The restrictions were imposed hours after Israeli forces killed at least nine Palestinians in attacks in northern and southern Gaza, medical sources told Al Jazeera.

At least six Palestinians were killed by Israeli forces in Gaza City and three others in Khan Younis.

Israeli soldiers killed five Palestinians near Gaza City’s Shujayeh neighborhood, a source at Ahli Arab Hospital told Al Jazeera Arabic on Tuesday.

The Israeli military said the shots were fired to neutralize a threat posed by personnel approaching forces in northern Gaza.

The attack came four days after a ceasefire between Israel and Hamas came into effect, paving the way for a prisoner exchange and a partial Israeli withdrawal from Gaza.

The ceasefire is the first phase of an end proposed by US President Donald Trump Israel’s war on GazaAccording to the Palestinian Health Authority, the epidemic has killed at least 67,913 people and injured 170,134 since October 2023. It is estimated that thousands of people’s remains lie beneath the rubble in Gaza.

A Hamas-led attack on October 7, 2023 killed at least 1,139 people in Israel and captured more than 200 others.

According to the terms of the ceasefire, Hamas and Israel carry On Monday, Israel released nearly 2,000 Palestinians held in Israeli prisons and 20 Israeli captives held in the Gaza Strip. Approximately 154 prisoners exile to Egypt.

Hamas is also scheduled to return the remains of 28 dead prisoners on Monday, but the group has only handed over four coffins.

Trump’s ceasefire plan provides a mechanism by which Hamas should share information about deceased captives if the transfer does not happen and make “best efforts” to make the transfer as soon as possible.

Hamas said it would transfer the remains of four more Israeli prisoners on Tuesday, and the Israeli military said the Red Cross had received them. The military later said the body had arrived in Israel, where it would undergo forensic examination.

The Israeli military earlier accused Hamas of violating the ceasefire “regarding the release of the bodies of hostages.”

In a post on his “Truth Social” platform, Trump pointed out the delay in handing over the remains of the deceased captives.

“As promised, the deceased has not returned yet! The second phase begins now!!!” he wrote.

Hamas has previously said retrieving the bodies of some prisoners may take more time because not all holding locations are known and because Israel has carried out extensive destruction of the enclave.

“The headlines here are that Israel has begun threatening to restrict aid entering Gaza over what they say is Hamas’ slow progress in bringing the bodies of deceased captives back to Israel,” Al Jazeera’s Gabriel Elizondo said, reporting from the United Nations.

UN urges more aid

The United Nations and the International Red Cross have called for all crossings into Gaza to be opened to allow much-needed aid into the enclave. Jens Laerke, a spokesman for the Office for the Coordination of Humanitarian Affairs, said on Tuesday that the United Nations had 190,000 tons of aid waiting to enter Gaza.

Meanwhile, the United Nations Children’s Fund (UNICEF) has prepared 1,370 trucks to enter Gaza, UNICEF spokesman Ricardo Pires said.

“The level of damage is so great again that it would take at least 600 trucks a day to do it, and that’s what we’re aiming for,” he said. “We’re still very far from that.”

The World Health Organization (WHO) has also stressed the need for more aid to Gaza.

“We need to expand the delivery of medical supplies because the pressure on hospitals will not ease overnight,” WHO spokesman Tarek Jasarevich told reporters.

“We really need to get as many supplies as possible right now to make sure those health workers who are still providing care have what they need.”
