Suicide blast hits elite Iranian force

TEHRAN, Iran — A suicide car bomber claimed by an al-Qaida-linked group attacked a bus carrying members of Iran’s elite Revolutionary Guard paramilitary force Wednesday, killing at least 27 people and wounding 13 others, state media outlets reported.

Tehran immediately linked the attack in Iran’s restive southeastern Sistan and Baluchistan province to an ongoing U.S.-led conference in Warsaw largely focused on Iran, just two days after the nation marked the 40th anniversary of its 1979 Islamic Revolution.

The bombing also raised the specter of possible Iranian retaliation targeting a Sunni militant group called Jaish al-Adl that claimed the attack, which largely operates across the border in nuclear-armed Pakistan. Recent militant assaults inside Iran have sparked retaliatory ballistic missile strikes in Iraq and Syria.

The bombing Wednesday night struck the bus traveling on a road between the cities of Khash and Zahedan, a mountainous region along the Pakistani border that is also near Afghanistan. Images after the blast published by semiofficial news agencies showed the explosion tore the bus apart, as passers-by used the lights of cellphones to illuminate the debris.

The state-run Islamic Republic News Agency, citing what it described as an “informed source,” offered initial casualty figures of 20 dead and 20 wounded. The Revolutionary Guard later reported on its website that 27 were killed and 13 wounded.
