Iran's Supreme Leader Ayatollah Ali Khamenei stressed in X that the "punishment" of Israel will continue.
This is Khamenei's first statement since the US bombed three Iranian nuclear sites over the weekend.
"The punishment continues. The Zionist enemy made a serious mistake, committed a great crime. It must be punished and is being punished," Khamenei wrote.
US President Donald Trump again praised the US strikes on Iran's nuclear facilities for causing "monumental" damage.
"Monumental damage was caused to all nuclear sites in Iran, as satellite images show. "Erasing is the right term!"
This is what Trump wrote on the social network "Truth".
The Director General of the UN International Atomic Energy Agency (IAEA), Rafael Grossi, said on Sunday that "at this time, no one, including the IAEA, is in a position to assess the underground damage" at Iran's Fordow nuclear site.
