On 2009, Tamil Nadu Government declared that the area is controlled by Sri Lanka against the original pact of allowing Indian fishermen to access the water of Sri Lanka.
This tension and the atrocious killings of Tamil fishermen by Srilakan forces has created disquiet across India and the governments of both the countries held talks.
Finally the Sri Lankan government allowed a full access term to Indian fishermen till Jaffna Line and released the fishermen jailed for a while.
