Feb. 13 (UPI) -- A suicide bomber killed dozens Iran's Islamic Revolutionary Guards Corps members aboard a bus in southeastern Iran on Wednesday, state-run media reported.
Initial reports said 20 were killed and 20 injured. The death toll was revised upward to 41 by Iranian media, implying that everyone aboard the bus died, The New York Times reported.
The bus was carrying personnel of the IRGC, an elite Iranian paramilitary force, between the cities of Zahedan and Khash near the border with Pakistan. It struck a roadside bomb, state-run FARS news agency reported, citing an IRGC statement that said an explosives-filled truck rammed the bus as it passed.
The IRGC immediately blamed the United States for the attack, noting that it occurred in the week Iran celebrated the 40th anniversary of the 1979 Islamic revolution that deposed the U.S.-backed shah.
A jihadist terrorist group prominent in the vicinity of the bombing, known as Jaish ul-Adl, took responsibility, Iran's Press TV reported. The group is supportive of the rights of Sunni Muslims in Iran, a predominately Shia Muslim country.
Iran has been criticized for provoking terrorism in the Middle East, but has also been a target. In September, IRGC members were attacked by gun-carrying terrorists during a military parade in Ahvaz in southwestern Iran. Twenty-five people died, including IRGC members and civilians, and about 60 were injured.
