Gaza's Hamas-run health ministry says 10,022 people have been killed in the territory since the war began a month ago, reports BBC.
The figure comes after a night of intense Israeli strikes, with the Israeli military saying they hit hundreds of targets including a Hamas military compound.
Israel's military carried out one of its heaviest bombardments of Gaza overnight.
The director of Gaza City's Al-Shifa hospital says the strikes killed about 200 people.
Casualties arrived at the hospital in carts carried by donkeys, the director told our reporter in Gaza, as communications outages left people unable to reach ambulance services.
Some politicians, including US President Joe Biden, have questioned the accuracy of the Gaza health ministry's figures.
The Israeli military said its troops took control of a Hamas outpost in Gaza and had now effectively divided the Strip in two.
Meanwhile, all major UN agencies have said "enough is enough" in a rare joint statement, as they repeat calls for a humanitarian ceasefire.
Israel began bombing Gaza after Hamas killed more than 1,400 people in Israel and kidnapped more than 200 others.
