At least 19 people were killed and dozens of others wounded in an Israeli airstrike on a Gaza mosque early on Sunday, Palestinian officials said.
The strike was carried out on the mosque near the Al-Aqsa Hospital in Deir al-Balah in the central Gaza Strip.
Eyewitnesses said the number of casualties could rise as the mosque was being used to house displaced people.
The Israeli military said in a statement it "conducted a precise strike on Hamas terrorists who were operating within a command and control center embedded in a structure that previously served as the 'Shuhada al-Aqsa' Mosque in the area of Deir al Balah."
Israel's military assault on Gaza has killed nearly 42,000 Palestinians, according to Gaza's health ministry. It has also displaced nearly all of the enclave's 2.3 million people, caused a hunger crisis and led to genocide allegations at the World Court that Israel denies.
The military meanwhile announced a new air and ground offensive in Jabaliya, in northern Gaza, home to a densely populated refugee camp dating back to the 1948 war surrounding Israel's creation. It circulated photos and video footage showing a column of tanks heading toward the area.
The military said its forces had encircled Jabaliya as warplanes struck militant sides ahead of their advance. Over the course of the war, Israel has carried out several large operations there, only to see militants regroup.
Israel also ordered new evacuations in northern Gaza, which largely emptied out in the early weeks of the war when Israel ordered its entire population to flee south. Up to 300,000 people are estimated to have remained there despite harsh conditions and heavy destruction.
“We are in a new phase of the war,” the military said in leaflets dropped over the area. “These areas are considered dangerous combat zones.”
Avichay Adraee, a spokesman for the Israeli military, said it has expanded the so-called humanitarian zone in southern Gaza, urging people to head there. The zone includes sprawling tent camps where hundreds of thousands of people have already sought refuge, and Israel has carried out strikes inside it against what it says are fighters sheltering among civilians.
