JAMMU, JAN 21: Security along the International Border (IB) in Jammu and Kashmir was beefed up following an alert by intelligence agencies about possible infiltration attempts by militants ahead of the 26th January, police said today. A group of three to four militants were seen camping across the border at a village in Pakistan, near a border out post (BoP), intelligence agencies are learnt to have warned the police and forces. The main reason behind ceasefire violations and shelling is to help infiltrate militants from across the border, IG, Jammu Zone, S D Singh Jamwal said. After the inputs from intelligence agencies, police have beefed up the security in border belts and increased round- the-clock vigilance, he said. The Jammu and Kashmir Police yesterday had sounded a “red alert” and asked border dwellers to move out of their areas as the situation was “sensitive” in the wake of continuous shelling.
