Director-General of Jammu and Kashmir Police Dilbag Singh had said the two terrorists were part of a suicide squad of Pakistan-based JeM and their infiltration could be a "big conspiracy" to sabotage the prime minister's visit to Jammu and Kashmir.
The PM is scheduled to visit Samba district's Palli village, 17 km from here, on National Panchayati Raj Day on April 24. He is also scheduled to address a gathering there.
According to officials, a multi-tier security setup has been put in place for Prime Minister Narendra Modi's visit.
An alert has been sounded along the border and a high degree of vigilance is being maintained at vital installations in Jammu and Kashmir in view of the visit, officials said on Friday.
