ISLAMABAD, 20 October 2021, (TON): The military's media wing revealed “the Pakistan Navy detected and blocked an Indian submarine from entering Pakistani waters on October 16 (last Saturday).”

The Inter Services Public Relations (ISPR) said the navy showed "unremitting vigilance and professional competence" in ascertaining and blocking the attempted entry of the Indian vessel.

The ISPR said "during the prevailing security milieu, a strict monitoring watch has been kept by Pakistan Navy to safeguard maritime frontiers of Pakistan."

It added that the Oct 16 incident was the third time an Indian naval submarine had been detected and tracked by the Pakistan Navy's long-range maritime patrol aircraft.

The statement reads "the recent incident reflects the deplorable Indian machinations vis-à-vis commitment and resolve of Pakistan Navy to defend maritime frontiers of the motherland.”

The last such reported incident occurred in March 2019 when the navy had detected and thwarted a similar attempted entry by an Indian submarine. "The Pakistan Navy used its specialised skills to ward off the submarine, successfully keeping it from entering Pakistani waters," a statement from the navy's spokesperson had said at the time.

Another attempt was made in November 2016 when an Indian submarine was tracked and pushed clear out of Pakistan's waters.
