Iran has condemned a “barbaric” Israeli airstrike on a school in Gaza housing displaced Palestinians that left dozens dead, calling it a “war crime”, AFP reports.

The attack showed once again that Israel “does not respect any of the rules and regulations of international law and moral and human principles”, foreign ministry spokesman Nasser Kanani said in a statement.

He said the strike was “a clear example of the simultaneous perpetration of genocide, war crimes and crimes against humanity” by Israel.

Kanani called for “firm action by Muslim and freedom-loving countries around the world to support the Palestinian nation and its legitimate struggles and resistance against the occupation”.
