Iran has repeatedly declared victory over Jundallah, the Sunni and Baluch group that claimed responsibility for a suicide bombing that killed at least 39 Shiite worshipers today.
Iran said it arrested top Sunni militant Abdolmalek Rigi, who claimed responsibility for a number of terrorist attacks inside Iran. Tehran claims Mr. Rigi received US support.
Iran said the guards were just chasing drug dealers when they crossed into Pakistani soil Monday. But some in Pakistan suspect it has to do with last week's deadly suicide bombing in Iran.
Iran says all three countries have links to a Sunni group blamed for Sunday's suicide blast that killed at least five senior members of Iran's Revolutionary Guard.
A Sunni insurgent group, Jundallah, claimed responsibility for Sunday's attacks that killed six of Iran's elite Revolutionary Guards and more than 20 others.
A force to reckon with in President Mahmoud Ahmadinejad’s second term, the Guards are led by commanders whose worldview was forged during the devastating Iran-Iraq war.
