QUETTA, (Raja Furqan Ahmed) : At least six suspected terrorists belonging to the militant Islamic State (IS) group were killed during an operation conducted by the counterterrorism department (CTD) in the Eastern Bypass area here on Saturday night. In a statement, a CTD spokesman said there was a heavy exchange of fire during the intelligence-based operation conducted on information about the presence in the area of the militants. The CTD also seized arms, ammunition and explosive material from a house being used by the members of the banned outfit as their hideout. A “huge terrorism plan” of IS had been averted in Quetta, the spokesman said. The operation was conducted by Balochistan’s CTD in Quetta district in the jurisdiction of Manzoor Shaheed police station, he added. The CTD said it acted on information provided by a source that an IS member named, Asghar Samalani, having head money of Rs2 million in the department’s Red Book, was present along with other militants in the general area of QDA graveyard on Quetta’s Eastern Bypass. “They were moving to attack a sensitive installation in Quetta. On receiving the information, a CTD team reached the place and intercepted the terrorists,” the spokesman said. The militants were asked to surrender by the CTD personnel, but they started firing indiscriminately and lobbed grenades. A shootout ensued in which six IS men, including Sumalani, were killed while four to five others managed to escape taking the benefit of darkness. Efforts were being made to identify the remaining IS members, the spokesman said. An FIR has also been lodged at a CTD police station in Quetta.
