The Pentagon is investigating a deadly airstrike that hit a girls' school in Iran on Saturday, killing at least 165 students according to Iranian officials, U.S. Defense Secretary Pete Hegseth said Wednesday.

Hegseth provided few details when questioned about the attack on the Shajareh Tayyebeh girls' school in Minab, stating only that the U.S. military was "investigating" and "taking a look" at the incident. Iranian officials have reported the death toll at between 165 and 170 people.

"All I can say is we're investigating that," Hegseth said when asked about the bombing. "We, of course, never target civilian targets, but we're taking a look and investigating that."

Neither the United States nor Israel has claimed responsibility for the strike. The attack represents one of the deadliest incidents involving civilian casualties in the ongoing regional conflict.

The UN office has reportedly demanded answers regarding the strike. The incident occurred amid heightened tensions in the region, though the specific circumstances and parties responsible for the attack remain under investigation by U.S. military officials.
