TEHRAN (Reuters) -- Iran has executed three people convicted of being involved in the bombing of a mosque that killed 14 Iranians in the southern city of Shiraz in 2007, the official IRNA news agency reported.
Tehran had accused the United States of arming and training those behind the blast and said Britain and Israel were involved in the bombing, which also injured 200 people.
Washington and London deny Tehran's accusations.
IRNA said the three were sentenced to death in November. Their sentences were upheld by Iran's Supreme Court.
A little-known Iranian Sunni Muslim dissident group had in June claimed responsibility for the blast.
Under Iran's Shari'a law, armed robbery, murder, adultery, drug smuggling, and involvement in "terrorist acts" are punishable by death.
