With the top US diplomat Antony Blinken in Israel for talks, scores of people have been reported killed in Gaza.
The Hamas-run health ministry says 126 people have been killed in Gaza in the last 24 hours.
It says 57 deaths were reported in one central Gaza hospital alone.
In Khan Younis in the south, Israel says it "eliminated 40 terrorists", and found Hamas tunnels and weapons.
After meeting Israeli President Isaac Herzog, Blinken's team says he "emphasised the need to take all feasible precautions to minimise harm to civilians".
Israel launched its offensive in Gaza after a cross-border assault by Hamas more than three months ago, which saw 1,300 people killed in Israel.
Since 7 October, more than 23,200 people - mostly women and children - have been killed in Gaza, according to the Hamas-run health ministry there.
Hamas leader urges Muslim states to provide weapons
Hamas leader Ismail Haniyeh has been speaking at a conference of Muslim scholars in Qatar - where he is based - telling an audience that Israel has “failed to achieve any of its goals” in the war in Gaza.
Haniyeh argues that the Hamas attacks of 7 October "came after an attempt to marginalise the Palestinian cause" and - referencing the hostages held in Gaza - says that Israel "will never recover their prisoners unless they release all of our prisoners".
In further comments later released by Hamas, Haniyeh called on Muslim states "to support the resistance with weapons, because this is... not the battle of the Palestinian people alone".
