Islamic Republic says “equipment” used in the drone attack on the Ministry of Defense complex in central Iran last week was procured by Kurdish groups based in Iraqi Kurdistan region.

Nour News Agency, affiliated with the Iranian Supreme National Security Council (SNSC), claimed on Wednesday that parts of a micro aerial vehicle and explosive materials were ordered by a foreign intelligence service and smuggled into Iran from the Kurdistan region through difficult mountain passes and were handed to an intermediary in a border city in the northwestern part of the country.

The report added that the drone parts and explosives were then assembled at a modern workshop by a group of specialists and were used in the attack.

Nour News had earlier claimed that several members of a “Kurdish group” were trained by Israel for sabotage operations on the industrial facilities of Esfahan but were “arrested by the Ministry of Intelligence,” a claim vehemently rejected by Kurdish groups.
