New Delhi, Dec 15 (PTI): The LTTE, which is almost on the verge of a wipe out, is trying to regroup and planning to launch spectacular strikes on high-profile targets like Prime Minister Manmohan Singh, home minister P Chidambaram and Tamil Nadu chief minister M Karunanidhi.

According to an intelligence input, some cadres of the LTTE, who escaped the wrath of the Sri Lankan Army during the all-out operations in the island nation earlier this year, were trying to regroup in India and planning attacks on top political leaders, particularly when they travel in Tamil Nadu.

The security agencies have taken the input seriously as former Prime Minister Rajiv Gandhi was assassinated by LTTE suicide squad members in the southern state in 1991.

Besides, Prime Minister Singh is also likely to visit Tamil Nadu next month to attend some public functions.

"Though LTTE is now a weak force and all top leaders were killed during the Sri Lankan Army's assault, attempts to regroup by some cadres is a disturbing report," an official said.
