People in the Gaza Strip continued to relocate from the north of the area on Monday as the Israel-Hamas war continues. Clashes between Israeli forces and Palestinian militants outside Gaza's largest hospital have prompted thousands of people to flee from the sprawling medical facility, but hundreds of patients and others displaced by the war remained inside, health officials said Monday. Shifa hospital has been without electricity and water for three days, and gunfire and bombings outside the compound “have exacerbated the already critical circumstances,” said World Health Organization Director-General Tedros Adhanom Ghebreyesus said on Sunday, adding that the U.N. agency was in contact with the hospital. Patients include dozens of babies at risk of dying because of a lack of electricity, health officials at the facility said. President Joe Biden on Monday said that Gaza’s largest hospital “must be protected,” and called for “less intrusive action” by Israeli forces. “It is my hope and expectation that there will be less intrusive action,” Biden said in the Oval Office. More than 11,000 Palestinians, two-thirds of them women and minors, have been killed since the war began, according to the Health Ministry in Hamas-controlled Gaza, which does not differentiate between civilian and militant deaths. About 2,700 people have been reported missing. Health officials, many of whom work out of Shifa, have not updated that toll since Friday because of the difficulty of collecting information. The ministry is the only official source for Gaza casualties. In previous wars, the ministry’s counts have held up to U.N. scrutiny, independent investigations and even Israel’s tallies. At least 1,200 people have died on the Israeli side, mostly civilians killed in the initial Hamas attack. Palestinian militants are holding nearly 240 hostages seized in the raid, including men, women, children and older adults. The military says 44 soldiers have been killed in ground operations in Gaza. The Israeli military has urged Palestinians to flee south on foot through what it calls safe corridors. But its purported drive to separate civilians from Hamas militants has come at a heavy cost, with more than two thirds of the territory’s population of 2.3 million having already fled their homes. The U.S. has pushed for temporary pauses that would allow for wider distribution of badly needed aid. Israel has only agreed to daily windows during which civilians can flee ground combat in northern Gaza along two main roads, while continuing to strike what it says are militant targets across the territory, often killing women and children.
