Approximately 60 militants are reported dead in the recent South Waziristan clashes. The military has also reported casualties with five dead and 11 injured. According to army officials, the resistance has not been as stiff, but this is expected to change once the offensive moves into Taliban strongholds such as Kotakai, Makin, Ladha and Manikurram.
