The bomber targeted a bus transporting military personnel on the Khash–Zahedan road in Sistan and Baluchestan province, near the border with Pakistan. The area is a refuge for militant separatist groups and drug smugglers. The bomber detonated a car full of explosives near the bus, killing 27 Revolutionary Guards and injuring 13. The soldiers were coming back to their cities after carrying out the border mission by the bus. Jaish al-Adl, a group connected to Al-Qaeda and involved in some of the recent terrorist activities in southeast Iran took responsibility for the suicide bombing. In October 2018, 11 Iranian border Guards were kidnapped by the group, only 5 of them were released. The Senior Revolutionary Guards commander of Iran claimed that the suicide bomber was a Pakistani national and one other member of the militant cell that planned the attack was also Pakistani. Furthermore, he claimed that three other members of militant cells were Iranian nationals from Sistan and Baluchestan. Out of those three Iranians, two were arrested.
