The strikes come as US talks over Iran's nuclear programme, which began in April, appear to have stalled in recent days. The next round of talks was scheduled for Sunday. US President Donald Trump has urged Iran to "make a deal" on its nuclear programme, "before there is nothing left". Other world leaders have called for restraint on both sides. IAEA head Rafael Grossi said nuclear facilities "must never be attacked" and such strikes have "serious implications for nuclear safety, security and safeguards, as well as regional and international peace and security". In a statement to board members, he called "on all parties to exercise maximum restraint to avoid further escalation", saying "any military action that jeopardises the safety and security of nuclear facilities risks grave consequences for the people of Iran, the region, and beyond".
