Israeli forces have thrust deeper into the Jabalia camp in northern Gaza on Tuesday, laying waste to residential districts with tank and air bombardments.
Israel said it has returned to the camp, where it had claimed to have dismantled Hamas months ago, to prevent the militant group that controls Gaza from rebuilding its military operations there.
Simultaneous Israeli assaults on the northern and southern edges of the Gaza Strip this month have caused a new exodus of hundreds of thousands of people fleeing their homes, and sharply restricted the flow of aid, raising the risk of famine.
The health authorities and Gaza Civil Emergency Service said dozens of bodies remained trapped under rubble of houses and on the roads in Jabalia, but rescue teams have been unable to reach them.
In Jabalia, a sprawling refugee camp built for displaced civilians 75 years ago, the Israeli army used bulldozers to clear shops and property near the local market, residents said, in a military operation that began almost two weeks ago.
Israel is seeking to eradicate Hamas after militants from the group stormed into southern Israel on Oct. 7, killing 1,200 and taking more than 250 hostages, by Israeli tallies.
