The Indian Army and the Indian Navy have been placed on high alert along the country's southern coast to prevent any infiltration bid by LTTE cadres fleeing the military offensive against them in Sri Lanka, a top commander said on Wednesday.

"There is a high alert in the southern command," reported the IANS yesterday (29) quoting Indian Army vice Chief Lt. Gen. Noble Thamburaj.

"The Coast Guard and the Indian Navy form the first tier (of defence). We have some troops deployed to ensure LTTE don't enter Tamil Nadu, he said.
