In an exclusive report, Iran's Nour News, which is affiliated with Iran's Supreme National Security Council, said the small-scale UAV used in the attack on the Ministry of Defense workshop complex in Isfahan was assembled and used in an equipped workshop, with the assistance of trained forces, after being transferred to the country by Kurdish opposition groups.

According to the news outlet, parts of small-scale UAVs, as well as explosive materials, entered Iran with the support and guidance of Kurdish opposition groups based in Iraq's Kurdistan region.

Additionally, upon orders from a foreign security service, and after receiving parts of the UAVs and explosive materials, the group smuggled them from one of the inaccessible routes in the northwest of Iran, and delivered them to a liaison in one Iran's border cities, according to the outlet.

It adds that the parts and materials were assembled in an equipped workshop using trained forces, and were used for the sabotage attack against the workshop complex.

A few days earlier, the Iranian Defense Ministry announced that it successfully thwarted a drone attack on a defense industrial complex in the central Iranian province of Isfahan.

In a released statement, the Ministry said one of three Micro Aerial Vehicles (MAVs) attacking the defense equipment manufacturing complex in Isfahan was downed by a defense system stationed inside the facility.

According to the statement, two other MAVs exploded after being caught in traps set by the system, pointing out that the unsuccessful attack failed due to the preparedness of the defense system stationed in the region.

Videos circulating on social media showed the moment the complex's defense system repelled the attack.
