A member of the Majlis National Security Committee said on Wednesday that Chabahar mosque suicide bomb was performed by the group Jundallah with the support of Qatar.
An Iranian lawmaker pointed out on Wednesday that Chabahar mosque suicide bomb was carried out by the Sunni rebels from the group Jundallah with the help of Qatar.
According to media, a suicide bomb outside a Shiite mosque in Iran killed two Basij militiamen and wounded five people, in an area that has been the target of deadly attacks by Sunni rebels in recent years.
Sistan-Baluchestan, which borders Pakistan and home to a strong Sunni minority in overwhelmingly Shiite Iran, has been the scene of bloody attacks by the Sunni rebels from the group Jundallah.
Jundallah chief Abdulmalek Rigi was hanged in June 2010 after he was captured on board a plane that was forced by Iranian armed forces to land as it crossed the Islamic Republic's airspace.
Tehran also accuses US, British and Pakistani intelligence of supporting the group.
