President Donald Trump said that the United States military struck three sites in Iran, directly joining Israel’s effort to decapitate the country’s nuclear programme in a risky gambit to weaken a longtime foe amid Tehran’s threat of reprisals that could spark a wider regional conflict.

Iran’s state-run IRNA news agency, quoting a provincial official, confirmed attacks on Fordo, Isfahan and Natanz nuclear sites.
