Prime Minister Benjamin Netanyahu has said Israel will intensify its fight against Hamas in the coming days.
He told members of his party that he had visited Gaza on Monday morning and that Israel’s military campaign there was “not close to being over”.
His comments come days after the US secretary of state said Israel should lower the intensity of its strikes.
The war began on 7 October after Hamas led a deadly attack on communities inside Israel.
Gaza’s Hamas-run health ministry said on Monday that some 20,674 Palestinians had been killed in Israeli bombardments since then. It says most of the fatalities have been women and children.
Some 1,200 people, mainly civilians, were killed when Hamas gunmen stormed across the border on 7 October. About 240 people were taken back to Gaza as hostages. Israel says 132 are still being held.
Mr Netanyahu has vowed to destroy Hamas and return the hostages to Israel.
On Monday he told a meeting of his Likud party that troops he met on his visit to Gaza had urged Israel to keep fighting.
