Colombo: Sri Lankan helicopters bombed Tamil Tiger positions in the north of the island on Saturday, the military said, a day after troops captured the rebel headquarters town of Kilinochchi.

The military is now targeting the port town of Mullaitivu and other rebel strongholds in the north to bring an end to the 25-year separatist war.

There has been no coment from the Liberation Tigers of Tamil Eelam (LTTE).

Sri Lanka military spokesman Brigadier Udaya Nanyakkara said troops were carrying out search and recovery operations in Kilinochchi town on Saturday and were preparing for attacks.

"We will take all possible measures to avert any more terrorist attacks, they (LTTE) are desperate now with the biggest defeats in northern war front so they will try more attacks," said Nanyakkara.

Sri Lankan troops captured the Tamil Tigers' headquarters town on Friday in one of the biggest setbacks for the rebels in years.

"It was the constant dream of all Sri Lankans, whether Sinhala, Tamil or Muslim, who are opposed to separatism, racism, and terrorism, and have always, sought peace, freedom and democracy," President Mahinda Rajapaksa said in a nationally televised address.

Within an hour of his statement, a suspected suicide attacker struck near the Sri Lankan Air Force headquarters, a spokesman at the Media Centre for National Security said.

Hospital officials said 37 people were wounded in the blast. The military said all three of those killed and 12 of the wounded were air force personnel.
