"Any Indian Muslim who believes in Islam would not allow any opportunity to the Islamic State to have a base in the country," the Union home minister said.
His remarks came in wake of claims that the global terror outfit was involved in an attack on security forces in Srinagar on November 17 in which a terrorist, Mugees, was killed and a sub-inspector, Imran Tak, lost his life.
Singh urged the young men, who live near the India- Pakistan border and who have been misled into joining terrorist groups, to return to the mainstream, saying proper assistance would be provided to them.
