"Two martyrs were recovered and 15 injured, including 10 children after Israeli planes struck the Salah al-Din school in Gaza City," agency spokesman Mahmud Bassal told AFP.

Meanwhile, medical and local sources said that at least 25 civilians were killed Wednesday evening in a series of Israeli airstrikes on homes, schools and tents sheltering displaced people in central and southern Gaza Strip, WAFA news agency reported.

In recent weeks, the Israeli military has struck several schools across Gaza, primarily in Gaza City.

On Tuesday, Bassal told AFP that a strike on the Mustafa Hafiz school in the city killed at least 12 people.  

And earlier this month Israel struck the Al-Tabieen school, also in Gaza City, in a massacre that killed more than 100 Palestinians and drew Arab and international condemnation.

Tens of thousands of displaced people have taken shelter in schools since Israel started its war on Gaza.

In southern Gaza, the Israeli warplanes launched a series of air raids on the eastern areas of Khan Yunis, killing of at least 21 civilians, WAFA said.

In the Nuseirat refugee camp in central Gaza, four civilians were killed in the Israeli bombardment of a house belonging to the Abu Rahma family in the market area of the camp.

Earlier in the day, the Palestinian Health Ministery announced that the Israeli army committed four massacres against families in the Gaza Strip over the past 24 hours, killing 50 people and injuring 124 others.

The number of people killed since the start of the Israeli aggression on the Gaza Strip on 7 October 2023 has surged to 40,223, mostly children and women. Some 92,981 others have been wounded.

Thousands of victims are still trapped under the rubble or scattered on the roads, as ambulance and civil defence teams are facing tremendous difficulties in reaching them due to the relentless Israeli shelling.

Casualty data in Gaza are incomplete due to the intensive Israeli aggression, the repeated and complete interruption of communication and internet services, devastated infrastructure and massive debris, and the lack of fuel and heavy machinery; which render it difficult to document figures.
