Over 100 Palestinians have been killed in northern Gaza — where Israel is currently laying a major siege — by Israeli attacks since the start of the weekend. More than 350 patients are believed to be trapped inside the three remaining partially operational hospitals in northern Gaza: the Indonesian, Al-Awda and Kamal Adwan hospitals. Dr. Ayaz Pathan, an emergency medicine physician who recently worked at the Indonesian and Nasser hospitals, describes the conditions he witnessed and responds to Israel’s latest attack on aid workers and four water engineers who were killed. “It was tragic to watch people be in pain, die in pain, die of infections which are completely preventable,” says Pathan.
