29 Palestinians killed in Israeli strike in Gaza's Khan Younis

An Israeli strike hits tents housing displaced families outside a school in the town of Abassan east of Khan Younis in southern Gaza, killing 29 Palestinians.

CAIRO - Twenty-nine Palestinians were killed by an Israeli strike that hit tents housing displaced families outside a school in the town of Abassan east of Khan Younis in southern Gaza on Tuesday, the director of the Hamas-run Gaza government media office told Reuters. 

On Gaza City's front lines, the armed wings of Hamas and its ally Islamic Jihad said their fighters battled Israeli forces with machine guns, mortar fire and anti-tank missiles and had killed and wounded Israeli soldiers.

Israel's military did not comment on casualties but said its soldiers were engaged in close-quarter combat with militants, had taken more than 150 fighters out of action in the last week and destroyed booby-trapped buildings and explosives.

The latest fighting has unfolded as senior US officials were in the region to push for a ceasefire after Hamas made concessions last week. But Israel's renewed campaign threatened talks at a crucial time and could bring negotiations "back to square one", Hamas quoted leader Ismail Haniyeh as saying.

Footage circulated on social media showed families packed onto donkey carts and in the backs of trucks piled with mattresses and other belongings making their way through Gaza City's streets to flee areas under Israeli evacuation orders.

"Gaza City is being wiped out, this is what is happening. Israel is forcing us to leave homes under fire," Um Tamer, a mother of seven, told Reuters via a chat app.

She said it was the seventh time her family had fled their house in Gaza City, in the north of the enclave and one of Israel's first targets at the start of the war in October.

"We can't take it anymore, enough of death and humiliation. End the war now," she said.

Israeli tanks pushed deeper into several city districts including Shejaia, Sabra and Tel Al-Hawa, where residents have reported some of the most fierce fighting in months.

The Palestinian Red Crescent said all of its medical clinics were out of service in Gaza City due to Israeli evacuation orders that have driven thousands of people westward towards the Mediterranean and to the south.

Nine months of war and displacement have caused a hunger crisis, and the recent deaths of several more children from malnutrition in the Gaza Strip indicate that famine has spread throughout the coastal enclave, a group of independent human rights experts mandated by the United Nations.

In a Khan Younis hospital, Palestinian woman Ghaneyma Joma told Reuters she feared her son would die of starvation.

"It's distressing to see my child...lying there dying from malnutrition because I cannot provide him with anything due to the war, the closing of crossings and the contaminated water," she said, seated on the floor next to her motionless son, who had an intravenous drip attached to his wrist.
