A committee of UN experts said it was “deeply disturbed” by the deaths of children amid escalating violence across the Middle East, particularly the bombing of a girls’ school in Iran.

The Shajareh Tayyebeh girls’ school in Minab in southern Iran was hit on Saturday, the first day of U.S. and Israeli attacks against the country.

It killed 160 children, UN experts stated.

U.S. Secretary of State Marco Rubio was asked about the incident on Monday.

“The Department of War would be investigating ​that if that was our strike, and I would refer your question to them,” he told ​reporters.

“The United States would not deliberately target a school,” he added.

The Pentagon and the U.S. Central Command did not respond to a request for comment. Over the weekend, the U.S. Central ​Command told media outlets it was “looking into” reports of “civilian harm resulting from ongoing military operations.”
