The Israeli military stated overnight on Sunday that it was carrying out another wave of attacks.
Earlier, the Iranian Red Crescent said the death toll at a school in Iran that was hit during the US and Israeli attack on Saturday had risen to 108. Most of those killed were schoolgirls, according to Iranian authorities, the Financial Times reports.
The AFP news agency has not been able to verify the death toll or the circumstances surrounding the incident.
The Israeli military has not yet commented on the reports.
According to the Iranian Red Crescent, at least 200 people have been killed and nearly 750 people injured in the US and Israeli attacks.
US Secretary of War Pete Hegseth says the US and Israel's attack on Iran sends a signal to those who want to harm Americans.
"If you kill or threaten Americans anywhere in the world - as Iran has done - we will find you and kill you," he writes on X.
Iran's UN Ambassador Amir Saeid accuses the US and Israel of committing war crimes.
The number of innocent civilians continues to rise. This is not just an aggression, it is a war crime and a crime against humanity," he said during an emergency meeting of the UN Security Council.
