In a Wednesday statement, Qassemi offered sympathy to the families of the victims and those injured in the tragic incident.
He condemned the inhumane attack by the terrorist group that claimed responsibility for it, and said the group receives military, financial, and intellectual support from certain regional states.
Such inhumane attacks will just make the Iranian nation and government more determined to continue its fight against terrorism in the region, he noted.
Qassemi also vowed that Iranian intelligence and military forces will definitely take revenge for the blood of the incident’s martyrs.
A suicide attack by Pakistan-based Takfiri elements on a bus carrying Iranian border guards in Iran’s Sistan and Baluchestan province has killed and wounded dozens of IRGC forces.
The attack, claimed by the so-called Jaish ul-Adl terrorist group, targeted the bus carrying IRGC border guards travelling between the cities of Zahedan and Khash in south-eastern Iran.
At least 27 have been killed and 13 other wounded in the blast.
The IRGC’s Quds Headquarters said in a statement that an explosive-laden car rammed into the bus, which was taking the personnel back to their homes.
Following the deadly attack, the governor-general of Sistan and Baluchestan declared three days of mourning.
