New Delhi, July 31 - More than two months after the Tamil Tigers were decimated, Tamils are still fleeing Sri Lanka to come to India, but mostly by air. And the number has reduced to a trickle.

Only 109 Tamils arrived in Tamil Nadu, the Indian state closest to Sri Lanka's shore, in May, the month Tigers chief Veluipillai Prabhakaran and all his top lieutenants were killed.

The number went up to 142 in June and it dropped to 89 in July - one of the lowest since the refugee influx began in right earnest in 1983 after the anti-Tamil violence in Sri Lanka.

But thanks to a tight naval blockade on the island's coastline, few Tamils cross the choppy sea now, said S.C. Chandrahasan, a Sri Lankan activist in India who has worked among the refugees for well over two decades.

Instead, they are heading to Colombo and boarding flights in what is a new phenomenon, Chandrahasan, who heads an organisation called OFFER, told IANS on telephone from Chennai.

'More people are now coming by flight because it is not easy to come by boat,' he said. 'It is very risky, costly and difficult to come through boats.'

Of the 109 who came in May, only 13 came by boat. In June, 39 of the 142 sailed to Tamil Nadu. The figure was just 10 in July.

Chandrahasan added that many of the estimated 280,000 in the refugee camps in northern Sri Lanka were making enquiries to find out if they could make it to India to start life afresh.

These are the people who have been kept in camps ever since the military overran the last of areas controlled by the Liberation Tigers of Tamil Eelam (LTTE) in May, ending one of the world's longest running insurgencies.
