Iranian officials say Iran's security forces are holding the head of a Sunni militant group. Iranian state media say Abdolmalek Rigi was arrested while traveling on a private airplane from Dubai to Kyrgyzstan. He leads Jundallah, a group blamed for a number of deadly attacks in Iran. The Iranian intelligence minister reportedly said that the militant leader was at an American military base twenty-four hours before his capture. The minister said that Americans had given him an Afghan passport. Iranian state television broadcast the comments. The French news agency is reporting that an American official dismissed Iran's accusations.
