Israeli tanks have surrounded hospitals in the Gaza Strip following a series of strikes on Palestinian medical facilities. The World Health Organization reports Al-Shifa in Gaza City — the territory’s largest hospital — remains under heavy bombardment. Thousands of Palestinians left homeless by previous attacks have been sheltering under tents in the hospital’s courtyard. The Al-Nasr Children’s Hospital in Gaza City reports it was attacked twice on Thursday and nearly had to halt operations, and the Al-Rantisi Children’s Hospital, home to Gaza’s only pediatric cancer ward, caught fire after an Israeli strike. Video shows patients and medical workers evacuating Al-Rantisi carrying white flags, then running in a panic as the sound of gunfire rings out. At least six of Gaza’s hospitals have come under fire in the past 24 hours. The Palestinian death toll is nearing 11,000, including 4,400 children.
