At least 10 people were killed Sunday in a fresh strike on a UN school in southern Gaza which was sheltering Palestinians displaced by an Israeli military offensive, medics said.

Gaza emergency services spokesman Ashraf al-Qudra said dozens of people were wounded in the attack which took place in the southern city of Rafah, which straddles the border with Egypt.

Chris Gunness, spokesman for the UN agency for Palestinian refugees (UNRWA), said the school had been housing thousands of internally displaced people (IDPs) who had been forced to flee their homes by the ongoing violence in Gaza. 

"Shelling incident in vicinity of UNRWA school in Rafah sheltering almost 3,000 IDP. Initial reports say multiple deaths and injury," he wrote on his Twitter feed.

It was the third time in 10 days that a UN school had been hit and came four days after Israeli tank shells slammed into a school in the northern town of Jabaliya, killing 16 in an attack furiously denounced by UN chief Ban Ki-moon as "reprehensible".
