The death toll from a missile strike on a girls’ school in southern Iran has risen to almost 150, according to Iranian state media.

Mizan news agency, the official news outlet of Iran’s judiciary, reported that the number killed in Saturday’s strike on a girls’ elementary school in Minab in southern Iran had risen to 148 killed, with 95 others wounded. The news agency cited Ebrahim Taheri, a prosecutor in Minab.

The school, which was struck on Saturday morning, appears to be the worst mass casualty event of the US-Israeli-led bombing campaign on Iran so far.
