Patrolling and deployment of troops along the Line of Control (LoC) in Jammu and Kashmir have been strengthened ahead of Republic Day, a senior BSF officer said on Wednesday.

"Terror outfits always try to carry out violence but jawans are alert on the border. Our endeavour is not to allow infiltration by terrorists. Such attempts are on from across the border but we prevent them forcefully," said Ashok Yadav, the inspector general of the BSF Kashmir Frontier.
