With Tamil Nadu due to go to the polls within weeks, the issue of Indian fishermen being attacked in the waters between India and Sri Lanka has once again made the news.
The oceanic border between India and Sri Lanka has no visible demarcations and fishermen often find themselves on the wrong side.
While Sinhala fishermen (often seeking tuna) have been arrested in Indian waters and later released, there has also long been a history of the Sri Lankan navy attacking and killing Indian fishermen.
