At least twenty-two people were killed and several others injured in two suicide attacks on the Pakistan-Iran border late Sunday night, officials said.

Home Secretary of southwestern Baluchistan province Akbar Hussain Durrani told reporters that the suicide bombers had targeted ten buses of Shiite pilgrims outside a hotel in Taftan, a town located about 350 kilometers from the state capital Quetta.

"Twenty-two people have been killed while several others have been injured in the suicide attacks," Durrani said, adding that the attacks were followed by heavy firing that might increase the death toll.

The Shiite pilgrims were on their way back from Iran after having visited the holy sites.

Mineral-Rich Baluchistan, has seen a separatist movement from secular Baluch militants resort to sectarian violence involving frequent attacks on Shiite pilgrims in the last decade.

Hardline group, Lashkar-e-Jhangvi has claimed responsibilities for most of the attacks on Shiites prompting security agencies to consider the organization responsible for the latest bombings.
