"As part of a joint strategy for recovery of snatched weapons, these operations are significant for restoring peace and would continue in a calibrated manner. Conducted under the surveillance cover of drones and quad-copters, the operations have so far resulted in recovery of 40 weapons (mostly automatic), mortars, ammunition and other warlike stores," a Defence spokesperson said. After Union Home Minister Amit Shah's appeal on Thursday, 144 sophisticated looted arms were surrendered in different districts till Friday evening. Meanwhile, the Defence spokesperson said that during the conduct of these operations, adequate measures were undertaken to ensure that the locals are not harassed and personal safety and security is maintained. Following the directions from Union Home Minister Amit Shah, security forces have once again appealed to all those in possession of snatched weapons to surrender the same at the earliest to ensure peace and stability in Manipur. Security forces also warned that failure to surrender these weapons would make all such people liable for strict legal action.
