Three members of the Islamic Revolution Guards Corps (IRGC) were killed in Iran’s southeastern province of Sistan and Balouchestan on Wednesday, Dec 18, after their vehicle was detonated by a booby trap bomb, Tasnim news agency reported.

A provincial security official said the deadly incident took place at 6:30 am local time, near the southeastern city of Saravan.

The three victims were members of the IRGC engineering division working on construction projects in the border area, the official said.

The vehicle carrying the IRGC staffers left a workshop in the morning, but was later detonated by a booby trap bomb on the road.

According to the public relations office of IRGC's Quds Base, the engineers "were involved in a project to seal part of Iran-Pakistan border in the frontier region of Saravan and that their car hit explosives left by bandits and traffickers on the road."

On Oct 25, a group of armed men carried out an ambush attack on a border post in Gazbostan, near Iran’s southeastern city of Saravan, on the frontier with Pakistan which has almost no control over its side of the shared frontier with Iran, killing 14 Iranian border guards.
