Israel sent tanks back into the greater Khan Younis area after ordering evacuations of some districts it said had been used for renewed attacks by militants, and at least 70 Palestinians were killed by Israeli fire, Gaza medics said on Monday.
The Palestinians were killed by tank salvoes in the town of Bani Suhaila and other towns fringing the eastern side of Khan Younis, with the area also bombarded from the air, they said.
Residents of the densely built-up area of southern Gaza said the tanks advanced for more than 2 kilometers into Bani Suhaila, forcing residents to flee under fire.
