Israeli forces have launched their storm of the main city in the southern Gaza Strip, where hospitals were overrun with scores of Palestinian wounded and dead, Reuters reports.

In what appears to be the biggest ground assault since a truce collapsed last week, residents said Israeli tanks entered the eastern parts of Khan Younis for the first time, crossing from the Israeli border fence and advancing west.

Some took up positions inside the town of Bani Suhaila on Khan Younis’ eastern outskirts, while others continued further and were stationed on the edge of a Qatari-funded housing development called Hamad City, residents said.
