"Afghan National Defense and Security Forces launched 12 Counter-Terrorism operations to clear some areas from terrorists and enemies and as a result 71 rebels have been killed over the past 24 hours," the statement said.

During the operations, which covered parts of Nangarhar, Helmand, Laghman, Farah, Kunduz, Ghor, Wardak and Zabul provinces, 40 more militants sustained injuries and seven others arrested.
