More than 300 children have been killed in Iran and Lebanon since the current conflict involving the United States and Israel began, according to a United Nations official.

Ted Chaiban, deputy executive director of UNICEF, told reporters at a press briefing in New York City on Monday that 324 children have died in the two countries. He said 206 children in Iran and 118 children in Lebanon have been killed since the conflict started.

The casualty figures highlight the civilian toll of the ongoing regional hostilities. UNICEF, the UN agency responsible for providing humanitarian aid to children worldwide, regularly tracks and reports on child casualties in conflict zones.

Among the reported deaths was an incident on February 28 in Minab, southern Iran, where a missile strike hit an elementary school, killing multiple children including a student named Soheil, according to his mother Zahra Monazzah.

The conflict has drawn in multiple regional actors and has resulted in casualties across several countries in the Middle East. UNICEF's casualty count represents children killed in Iran and Lebanon specifically since hostilities began.
