Israeli’s attacks come as military readies for an expected ground offensive on the besieged enclave.
The Hamas government press office said in a statement that “more than 55” people were killed in Saturday night’s attacks.
The casualties add to the more than 4,300 Palestinians, mostly civilians, who have been killed in Israel’s bombing campaign on Gaza, according to Gaza’s Ministry of Health.
Israel has pledged to eliminate Hamas after the armed group’s October 7 attacks inside the country, which Israeli officials say killed more than 1,400 people, mostly civilians.
Israeli air raids have damaged or destroyed 40 percent of Gaza’s housing, according to the United Nations, reducing much of the enclave to ruins.
Israel has ordered 1.1 million Palestinians in Gaza to evacuate southwards as it readies for a ground incursion into the enclave for the first time in nearly a decade.
However, the southern portion of Gaza has not been spared from air attacks, with nine people killed in the southern city of Khan Younis on Saturday night, according to Hamas authorities.
Israel’s military has pledged to intensify air raids in the coming days to minimise risks to its troops when they move in on Gaza.
The expected ground offensive has raised fears of more civilian deaths due to the limited options for safe haven in the densely populated enclave, which has been under an Israeli blockade since 2006. More than one million people have been displaced in Gaza, according to UN estimates.
“From today, we are increasing the strikes and minimising the danger,” Israeli military spokesperson Admiral Daniel Hagari said on Saturday.
“We will increase the attacks and therefore I called on Gaza City residents to continue moving south for their safety.”
Israeli troops are expected to encounter numerous challenges during a ground invasion, including the presence of Hamas booby traps and tunnels. The safety of an estimated 200 captives being held by Hamas is another complicating factor.
“Gaza is densely populated, the enemy is preparing a lot of things there – but we are also preparing for them,” Israeli Lieutenant-General Herzi Halevi said.
