The Obama administration announced Sunday that it was imposing new, more limited sanctions on some Iranian citizens and companies for violating United Nations resolutions against ballistic missile tests. The move came less than 24 hours after the White House lifted broader sanctions against Iran for its nuclear program.The announcement, which was prepared several weeks ago but delayed by the Treasury Department, was made shortly after a Swiss plane carrying Americans freed by the Iranian authorities departed Tehran. The release of the Americans came a day after Iran and the United States concluded delicate negotiations on a prisoner exchange tied indirectly to the completion of a nuclear agreement.
