According to reports, the Israeli shelling hit Abu Hussein School in Jabalia, located 4 kilometers North of Gaza City early on Wednesday, press tv reported.
Scores of people also suffered injuries in the deadly attack on the UN-run school, which was used as a shelter by Palestinian families against the Israeli offensive.
This is the second time in less than a week that the Israeli army is targeting a UN-run school. On July 24, Israeli tank shells slammed into a school in Beit Hanoun in the Northern Gaza Strip. Sixteen people were killed and hundreds of people were also wounded in the attack. The school was also used as a shelter for Palestinian families forced to leave their homes due to Israel’s deadly offensive in the enclave.
Twelve more Palestinians were also killed in separate Israeli attacks on Wednesday.
Reports say that three mosques were also destroyed in overnight Israeli strikes on the blockaded enclave.
Since July 8, Israel has been targeting the Gaza Strip with military attacks. The air, sea and land strikes by Israel have so far killed more than 1,260 people and injured thousands of others in the coastal sliver.
The Ezzedine al-Qassam Brigades, the military wing of the Palestinian resistance movement Hamas, has been launching retaliatory attacks against Israel. Tel Aviv confirms 53 Israeli soldiers have been killed in Gaza war, but Hamas puts the number at around 100.
