Several top commanders in Iran’s elite Revolutionary Guards have been killed in a suicide bombing in the volatile south-east of the country.
Iranian state television said 31 people died in the attack, in the Pishin region of Sistan-Baluchistan, and more than 25 were injured.
Shia and Sunni tribal leaders were also killed. A Sunni resistance group, Jundullah, said they carried it out.
President Mahmoud Ahmandinejad said the criminals would be punished.
