Trump says nothing can jeopardise Gaza ceasefire after deadly Israeli strikes

US President Donald Trump has said that "nothing is going to jeopardise" Gaza's ceasefire after deadly overnight Israeli strikes rocked the coastal enclave.

In comments made to reporters on Air Force One on Wednesday, Trump said: "You have to understand Hamas is a very small part of peace in the Middle East, and they have to behave."

Israeli strikes killed at least 100 people across Gaza on Tuesday, according to the Palestinian civil defence, which said the figure includes 35 children.

The strikes came after a reported clash between Palestinian militants and Israeli forces in Rafah, with the Israeli army saying that a reservist was killed in the clash.

The attack was carried out by a cell that emerged from a tunnel in Rafah during an army operation to destroy the tunnels, according to Israeli media outlet Walla.

The report adds that it is unknown if the attack was coordinated with Hamas's leadership, although they have denied carrying out the attack.

"As I understand it, they took out an Israeli soldier," Trump said.

Doubling down on his support for Israel, Trump added: "So the Israelis hit back and they should hit back. When that happens they should hit back."

"If they (Hamas) are good, they are going to be happy, and if they are not good, they are going to be terminated, their lives will be terminated."

Strikes were reported across the length of the Gaza Strip overnight, with Palestinian news agency Wafa reporting that Israeli forces struck targets in the Nuseirat refugee camp, where at least 18 Palestinians, including women and children, were killed.

The agency added that strikes also targeted a camp east of the al-Aqsa Martyrs hospital in Deir el-Balah, killing at least five, while strikes also hit the al-Bureij refugee camp, Khan Younis, Al-Mawasi and Gaza City.

Mohammad al-Munirawi, a journalist for Palestine Newspaper, was killed in an Israeli strike, according to Gaza's Government Media Office, with reports adding that his wife was also killed.

The extensive Israeli airstrikes came after Israel's far-right launched a pressure campaign to restart the war following allegations of Hamas violations surrounding the return of the remains of Israeli captive Ofir Tzarfati.

Hamas said that it handed over one body of 13 dead hostages, but anonymous sources quoted in the Israeli press later claimed that tests done by the national forensic institute showed that the coffin contained the partial remains of Tzarfati, whose remains had previously been returned to Israel.

Israel labelled the return a violation of the ceasefire, while also releasing footage of what it claimed was Hamas fighters placing the body bag in a hole dug in Gaza City, covering it with dirt, and then uncovering it in front of the Red Cross.

On Wednesday, the Red Cross issued a statement saying "it is unacceptable that a fake recovery was staged".

The organisation also described its work in Gaza as "exceedingly challenging" and that it "is raising its concerns directly with the parties".

"The ICRC also reiterates its call on the parties to uphold their commitments to the ceasefire agreement and facilitate the return of the deceased. The ICRC can only carry out its responsibilities with the cooperation of all involved," the statement added.
