At least 27 Islamic Revolutionary Guards Corps members were killed after a suicide attack on a bus carrying the troops home from a border mission, according to Iranian news sources and official statements. The Guards Corps have blamed the U.S. for the attack, mentioning the suspicious timing of the attack with the country’s 40th anniversary of its revolution and the anti-Iran meetings occurring in Poland with the country’s regional adversaries. Shortly after the attack, a Sunni extremist group operating in the area claimed responsibility for the attack. The group maintains links with Al Qaeda and have been suspected in earlier terrorist attacks in the country. Iran accuses Israel, the U.S. and Saudi Arabia of supporting the group carry out terrorist activities in Iran.
