Israeli warplanes and artillery fire have pummeled densely populated areas of Gaza City’s Sabra and Shuja’iyya neighborhoods in a surprise attack that forced tens of thousands of Palestinians to flee their homes while Israeli ground forces were seen advancing. Al Jazeera reports at least eight people were killed, with many more missing and believed to be buried under rubble. In southern Gaza, there are reports of civilian deaths in Khan Younis after Israel’s military struck a school housing displaced people.

Meanwhile, Reuters reports a Palestinian girl died of malnutrition in Kamal Adwan Hospital late Wednesday, becoming the fourth documented case of a child in Gaza dying from starvation or dehydration this week alone. The U.N. warns nearly all of Gaza’s 2.3 million residents are going hungry, with a half a million facing “catastrophic levels of acute food insecurity.”
