Israeli forces have widened their raid into northern Gaza, and tanks reached the north edge of Gaza City, pounding some districts of the Sheikh Radwan neighbourhood, residents said, forcing many families to leave their homes.
Residents said Israeli forces have effectively isolated Beit Hanoun, Jabalia, and Beit Lahiya in the far north of the enclave from Gaza City, blocking access between the two areas except upon their permission for families willing to leave the three towns, heeding evacuation orders.
Gaza's health ministry said the eight-day-old Israeli incursions in the north have so far killed dozens of Palestinians, with dozens of others feared dead on roads and under rubble of their houses, beyond the reach of medical teams.
Many Jabalia residents posted on social media platforms: "We will not leave, we die, and we don't leave."
The escalation in northern Gaza has taken place alongside a huge Israeli air assault and ground campaign on a separate front in southern Lebanon against Hezbollah.
"As the world is focused on Lebanon and possible Israeli strike against Iran, Israel is wiping out Jabalia," said Nasser, a resident of Beit Lahiya in the northern Gaza Strip.
"The occupation is blowing up roads and destroying residential districts. People also don't find anything to eat, they are trapped inside their homes, fearing bombs could fall onto their heads," he told Reuters via a chat app.
The Israeli military said in a statement on Sunday that forces operating throughout the Gaza Strip in the past 24 hours had attacked about 40 targets and killed dozens of Hamas fighters.
Palestinian and United Nations officials say there are no safe areas in Gaza. They have also voiced concerns over severe shortages of food, fuel, and medical supplies in northern Gaza, and said there is a risk of famine there.
Some tank shells landed in some streets of the Gaza City suburb of Sheikh Radwan, where tanks arrived at the edges of the territory, residents said, spreading panic among the population further south.
