Iran's Islamic Revolutionary Guards Corps (IRGC) has called on Pakistan to tackle suspected militants who kidnapped 14 members of Iranian security forces on October 16 on their shared border.
"We expect Pakistan to confront these terrorist groups that are supported by some regional states and immediately release the kidnapped Iranian forces," the IRGC said in a statement carried on state television.
Iranian state media earlier reported that the 14 border guards, including IRGC intelligence officers, were kidnapped on the southeastern border with Pakistan.
The official IRNA news agency said the border guards were "abducted between 4 a.m. and 5 a.m. in the Lulakdan area of the border by a terrorist group."
Lulakdan is located 150 kilometers southeast of Zahedan, capital of the southeastern province of Sistan-Baluchistan.
Of the 14, two were members of the elite IRGC intelligence unit and seven were volunteers in the Basij militia involved in "a security operation."
The reports did not name a specific group as a suspect in the abduction.
The area has seen occasional clashes between Iranian forces and Baloch separatists, as well as drug traffickers.
In September, militants disguised as soldiers opened fire on a military parade in Iran's oil-rich southwest, killing 24 people and wounding more than 60.
