Israeli strike kills at least 33 people at Gaza school

An Israeli strike early Thursday on a school sheltering displaced Palestinians in central Gaza killed more than 30 people, including 23 women and children, according to local health officials. 

The Israeli military said that Hamas militants were operating from within the school.

It was the latest instance of mass casualties among Palestinians trying to find refuge as Israel expands its offensives in the Gaza Strip. A day earlier, the military announced a new ground and air assault in central Gaza, pursuing Hamas militants it says have regrouped there. 

Troops repeatedly have swept back into sections of the Gaza Strip they have previously invaded, underscoring the resilience of the militant group despite Israel's nearly eight-month onslaught in the territory.

Witnesses and hospital officials said the predawn strike hit the al-Sardi School, run by the United Nations agency for Palestinian refugees known by the acronym UNRWA.

 The school was filled with Palestinians who had fled Israeli offensives and bombardment in northern Gaza, they said.

Casualties from school strike arrived at the Al-Aqsa Martyrs Hospital in nearby Deir al-Balah, which had already been overwhelmed by a stream of constant ambulances since the central Gaza incursion began 24 hours earlier, said Omar al-Derawi, a photographer working for the hospital. 

Videos circulating online appeared to show several wounded people being treated on the floor of the hospital, a common scene in Gaza's overwhelmed medical wards.

Electricity in much of the hospital is out because staff are rationing fuel supplies for the generator.

Hospital records and an Associated Press reporter at the hospital recorded at least 33 dead from the strike, including 14 children and nine women. Another strike on a house overnight killed six people, according to the records.

Both strikes occurred in Nuseirat, one of several built-up refugee camps in Gaza dating to the 1948 war surrounding Israel's creation, when hundreds of thousands of Palestinians fled or were driven from their homes in what became the new state.

The Israeli military said Hamas had embedded a compound within the school and that Hamas and Islamic Jihad militants inside were using it as a shelter where they were planning attacks against Israeli troops, though it didn't immediately offer evidence.

It released a photo of the school, pointing to classrooms on the second and third floor where it claimed militants were located.

UNRWA schools across Gaza have functioned as shelters since the start of the war, which has driven most of the territory's population of 2.3 million Palestinians from their homes.

Last week, Israeli strikes hit near an UNRWA facility in the southern city of Rafah, saying they were targeting Hamas militants. An inferno that followed ripped through tents nearby housing displaced families, killing at least 45 people.
