The 11 were connected to Jundollah, a Sunni group also known as the People's Resistance Movement of Iran, the Iran Labour News Agency reported.

Most of them "had played a part in killing innocent people, members of Iran's security forces, as well as kidnapping, gunrunning, drug smuggling" and other offenses, it said.

The news agency quoted the head of Sistan-Baluchestan province, Hojatoleslam Ebrahim Vahidi, as its source on the executions.

The executions come about a week after bombings outside the Imam Hussein Mosque in Chabahar in southeastern Iran killed at least 32 people, an attack that authorities blamed on Jundollah.

The US designated Jundollah as a foreign terrorist organization in November. The US State Department says since the group's inception in 2003, it has killed or maimed Iranian civilians and government officials through suicide bombings, ambushes, kidnapping and assassinations.
