US President Donald Trump says American warplanes have bombed three nuclear sites in Iran, marking a significant escalation in the ongoing war between Iran and Israel.
One of the targets was Fordo - a uranium enrichment plant hidden in a remote mountainside that is vital to Iran's nuclear ambitions.
Two other key nuclear sites - Natanz and Isfahan - were also hit Israeli officials say they were in "full co-ordination" with the US in planning these strikes.
The US contacted Iran through diplomatic channels on Saturday to say the air strikes were all it intended to do and that "regime change efforts" were "not planned", according to US officials speaking to the BBC's US partner, CBS News.
We do not yet know the full scale of the damage at the facilities, but the UN nuclear watchdog says there has been "no increase" in off-site radiation levels reported.
