ISLAMABAD: Security forces have killed 15 militants during a series of intelligence-based operations (IBOs) conducted across several districts of Balochistan, security sources said on Sunday. The operations were carried out under Operation Rad-ul-Fitna-3 in Mastung, Bolan, Washuk, Awaran, Sibi, Khuzdar, Harnai and Nushki, according to the sources. A substantial cache of weapons and ammunition was also recovered during the operations, while security forces reportedly dealt a major blow to militant networks operating in the province. Interior Minister Mohsin Naqvi commended the security forces for the successful operations, saying their actions had disrupted the plans of militants affiliated with Fitna al-Hindustan and Fitna al-Khawarij. In a separate operation two days earlier, security forces killed three militants and detained 12 suspects during a search and sanitisation operation in the Kambela and Asimabad areas of Mastung, security sources said.
