The latest:

• Israeli military blames Hamas rocket fire for renewed evacuation directive.
• Director of major north Gaza hospital injured in Israeli drone strike, health officials say.
• Two reported injured after missile strike on mosque in central Gaza.
• Palestinians say hospitals in north Gaza barely functioning.
• Israeli airstrikes kill 10 people in central Gaza, say medics.

The Israeli military issued new evacuation orders to residents in areas of an eastern Gaza City suburb, setting off a new wave of displacement on Sunday, and a Gaza hospital director was injured in an Israeli drone attack, Palestinian medics said.

The new orders for the Shejaia suburb posted by an Israeli army spokesperson on X on Saturday night blamed Palestinian militants firing rockets from that heavily built-up district in the north of the Gaza Strip.

"For your safety, you must evacuate immediately to the south," the military's post said.

The rocket volley on Saturday was claimed by Hamas's armed wing, which said it had targeted an Israeli army base over the border.

Footage circulated on social and Palestinian media, which Reuters could not immediately verify, showed residents leaving Shejaia on donkey carts and rickshaws, with others, including children carrying backpacks, walking.

Families living in the targeted areas began fleeing their homes after nightfall on Saturday and into Sunday's early hours, residents and Palestinian media said — the latest in multiple waves of displacement since the conflict began 13 months ago.

In central Gaza, health officials said at least 10 Palestinians were killed in Israeli airstrikes on the urban camps of Al-Maghazi and Al-Bureij since Saturday night.

Missile strike on mosque 

Elsewhere in central Gaza, a strike on the al-Farouq mosque in Nuseirat left two injured on Saturday. 

Footage gathered by CBC freelance videographer Mohamed El Saife shows a missile hitting the base of the mosque and dust gathering quickly as Palestinians ran to assess the damage.

Footage shows strike on mosque in central Gaza

Video obtained by CBC News and Reuters shows the moment a mosque in Nuseirat, Gaza, was hit by an airstrike. Witnesses say they were told to evacuate the area by the Israel Defence Forces before the strike.

Witnesses told El Saife the strike came after the noon prayers, so the mosque was mostly empty by then. They said there were warnings from the Israel Defence Forces before the strike to evacuate the area.

Mohamed Abu al-Ru'us, a congregant at the mosque, called the attack "aggressive" and "barbaric."

Some people at the scene carried torn-up pages of the Qur'an that were inside the mosque.

Hundreds of tents flooded

Adding to the miseries of Gaza's 2.3 million people, most of whom have been repeatedly displaced, heavy winter rain flooded hundreds of tents across the enclave, spoiling food and sweeping away plastic and cloth sheeting that had protected them against the elements.

"We ran in the middle of the night, the rainwater flooded the tent, the food is gone, the kids screamed and I am afraid they will get sick," Rami, 37, a Gaza City man displaced at a former soccer stadium, told Reuters via a messaging app.

The Palestinian Civil Emergency Service said thousands of displaced people were impacted by the seasonal flooding and demanded new tents and caravans from aid donors to shield them.

In north Gaza, where Israeli forces have been operating against regrouping Hamas militants since early last month, health officials said an Israeli drone dropped bombs on Kamal Adwan Hospital, injuring its director Hussam Abu Safiya.

"This will not stop us from completing our humanitarian mission, and we will continue to do this job at any cost," Abu Safiya said in a video statement circulated by the Health Ministry on Sunday.

"We are being targeted daily. They targeted me a while ago, but this will not deter us," he said from his hospital bed.

Israeli forces say armed militants use civilian buildings including housing blocks, hospitals and schools for operational cover. Hamas denies this, accusing Israeli forces of indiscriminately targeting populated areas.

Kamal Adwan is one of three hospitals in north Gaza that are barely operational as the Health Ministry said the Israeli forces have detained and expelled medical staff and prevented emergency medical, food and fuel supplies from reaching them.

In the past few weeks, Israel said it had facilitated the delivery of medical and fuel supplies and the transfer of patients from north Gaza hospitals in collaboration with international agencies such as the World Health Organization.

Residents in three embattled north Gaza towns — Jabalia, Beit Lahiya and Beit Hanoun — said Israeli forces had blown up hundreds of houses since renewing operations in an area that Israel said months ago had been cleared of militants.

Palestinians say Israel appears determined to depopulate the area permanently to create a buffer zone along the northern edge of Gaza, an accusation Israel denies.

Israel's campaign in Gaza has killed more than 44,000 people, uprooted nearly the entire population at least once, according to Gaza officials, while reducing wide swaths of the narrow coastal territory to rubble.

The war erupted in response to a cross-border attack by Hamas-led militants on Oct. 7, 2023, in which gunmen killed around 1,200 people and took more than 250 hostages back to Gaza, according to Israeli tallies.
