At least 22 Palestinians, including women and children, have been killed after Israel launched air and drone attacks across Gaza, while a power outage threatens the lives of more than 100 patients at a hospital in the besieged territory's north. In the latest Israeli attack in the Jabalia refugee camp in northern Gaza on Monday morning, three people were targeted with a missile launched from a drone, instantly killing them, sources told Al Jazeera. "[The victims] were trying to leave their home in search of food in the vicinity of their neighbourhood when they were targeted by a drone," said Al Jazeera's Hani Mahmoud, reporting from central Deir el-Balah in Gaza. "They were killed right away. Their bodies are still in the street and nobody has the ability to get to the bombed site and remove the bodies from the street."
