Rameswaram (TN), Jan 14 (Agencies): After a fisherman was killed by Sri Lankan Naval personnel, Indian Navy will strengthen security along the south-eastern coast.

"We will strengthen security along the South-Eastern coast," Chief Staff Officer (Operations) of Eastern Naval Command (Visakhapattinam) SV Dhokare said after reviewing coastal security measures.

The senior Naval official undertook the exercise a day after India lodged a strong protest with Sri Lanka over the killing of a Tamil Nadu fisherman allegedly by the island Navy.

Dhokare said the Navy had informed the Centre about the incident in which a fisherman from Jagadapattinnam near Pudukottai was killed in alleged firing by Sri Lankan Naval personnel on Wednesday.

He said the Government had taken up the issue with Sri Lanka.

Dhokare also made an aerial survey of the sea around Rameswaram along with senior Naval officers and visited the nearby Naval Air Station at Uchipuli and Naval Detachment here and held discussions with senior officials, including S Agarwal, Commanding Officer of Naval Detachment.

New Delhi urged Sri Lankan authorities to ‘desist’ from use of force against fishermen.

The incident also evoked a strong reaction from Tamil Nadu with Chief Minister M Karunanidhi sending a telegram to Prime Minister Manmohan Singh for strong action to end such atrocities.

The Sri Lankan envoy, however, denied involvement of his country's Navy in the killing of the fisherman.

Meanwhile, Indian Coast Guard DIG and Commander of ICG ship 'Vikram' Raj said the fishermen crossed Indian territorial waters resulting in attacks by Lankan Navy. "However, it is wrong to shoot innocent fishermen," he said and appealed the fishermen not to cross the International Maritime Boundary Line.
