TEHRAN - A suicide attack in south-eastern Iran has killed at least 27 members of the Revolutionary Guards and wounded 13 others, state media say.
The bomber targeted a bus transporting personnel in Sistan-Baluchestan province near the border with Pakistan.
The Sunni Muslim militant group, Jaish al-Adl (Army of Justice), has said it was behind the bombing.
The Revolutionary Guards, which is a major military, political and economic force in Iran, blamed foreign powers.
What do we know about the attack?
The Revolutionary Guards branch in south-eastern Iran said a unit of its ground forces had been returning from the Pakistan border area on Wednesday when a car filled with explosives blew up beside their bus on the Khash-Zahedan road.
In a statement, it blamed "takfiri terrorists and mercenaries of the intelligence services of hegemonic powers". "Takfiri" is a term used to describe Sunni extremists who see other Muslims as non-believers.(FA)
