Communications and internet networks in Gaza will be cut off by Thursday due to infrastructure damage and a lack of fuel, the Palestinian communications minister in Ramallah, Ishaq Sider, warned Sunday. Health-care infrastructure in Gaza City is facing collapse as fierce fighting rages around hospitals with dwindling food, fuel and water supplies. Gaza’s Health Ministry said its largest hospital, al-Shifa, was an “open war zone” on Sunday, a day after the ministry’s director general told The Washington Post that Israeli forces were “striking us from all sides.” Israel denied that its forces were targeting or blockading al-Shifa.
