Tel Aviv/IBNS: Israel's Prime Minister Benjamin Netanyahu Monday said that a ceasefire in its war with Gaza war "will not happen" as it would mean "to surrender" to Hamas.

Speaking at a press conference, Netanyahu said that other countries must provide more help in the struggle to free more than 230 hostages seized by Hamas in its October 7 attacks.

He said the international community must demand the captives "be freed immediately, unconditionally".

This comes after the United Nations ramped up appeals for a humanitarian ceasefire in Gaza after another night of ground incursions and intense bombardment by Israeli forces left healthcare facilities without electricity and civilians across the ravaged enclave virtually “cut off from the outside world”.

Secretary-General António Guterres said: “I reiterate my strong appeal for an immediate humanitarian ceasefire, together with the unconditional release of hostages and the delivery of relief at a level corresponding to the dramatic needs of the people in Gaza, where a humanitarian catastrophe is unfolding in front of our eyes.”

Israel Friday night launched massive strikes across northern Gaza which according to reports were the most "intense" since the start of the war with Hamas on October 7.

The Israeli army accused Hamas of abusing hospitals in the Gaza Strip for military purposes. The allegation was swiftly denied by Hamas, and the main United Nations agency working in Gaza said earlier it had mechanisms in place to prevent aid being diverted.

On October 7, Palestinian movement Hamas launched a surprise large-scale rocket attack against Israel from the Gaza Strip.

Israel launched retaliatory strikes and ordered a complete blockade of the Gaza Strip, home to more than 2 million people, cutting off supplies of water, food, and fuel.

The escalation of the conflict has resulted in thousands of people being killed and injured on both sides.
