Government today extended the ban on LTTE by another two years following intelligence reports that remnants of the Sri Lankan Tamil terror outfit were trying to re-group in Tamil Nadu.

According to a notification issued by the Union Home Ministry, even though LTTE has been "decimated in Sri Lanka, recent reports reveal that remnant LTTE cadres and leaders are regrouping in Tamil Nadu".

The Liberation Tigers of Tamil Eelam has been banned since 1992 under the Unlawful Activities (Prevention) Act, 1967.

The outfit which was espousing the cause of a separate Tamil Eelam was vanquished by the Sri Lankan military in May last year.

The notification said the possibility of its remnant cadres using India and especially Tamil Nadu as a rear base for their re-grouping activities cannot be ruled out.

It also said the possibility of their entering in the guise of Tamil refugees also cannot be ruled out

Sources said LTTE sympathisers were posing a security threat by continuing to spread anti-India propaganda on the Internet accusing the Indian eadership and its officialdom of being responsible for their defeat.

They said activities of certain remnant cadres have been noticed in Tamil Nadu and a extension of ban on LTTE was required.

As per the procedure, the notification will now reach a Tribunal, which has to ratify it.

The group-led by V Prabhakaran had been proscribed as a terrorist organisation by several countries including the United States.

The LTTE was involved in the assassination of former prime minister Rajiv Gandhi in May 1991 following which it was banned in India in 1992.
