evidence: Sources said the case of two missing Keralites from the UAE and Qatar a few months ago had increased suspicion that radicalised Kerala youths were joining the IS militants. Intelligence agencies had already traced the identity of Abu Thahir, who had left his home at Puduppariyaram, near Palakkad in Kerala for Qatar, two years ago. But the Indian Consulate in Qatar had no clue if he had reached the Emirate, even as his Facebook page remained active for long after he was reported missing. Another is an unnamed Keralite youth hailing from Kunnummal in Kozhikode District. He has been missing from Ras-al-Khaimah in UAE for the past four months. Sources said that a Keralite's name figured in the radar of intelligence agencies after the detention of IM sympathisers in Saudi Arabia. It was unclear whether he was still alive, sources said.
