WASHINGTON (Reuters) -U.S. B-2 bombers were involved in strikes on Iran's nuclear sites announced by President Donald Trump on Saturday, a U.S. official told Reuters, speaking on condition of anonymity.

Reuters had reported earlier on Saturday the movement of B-2 bombers, which can be equipped to carry massive bombs that experts say would be ideal to strike the sites.
