India has erected a barbed wire fence inside Indian territory to check cross border infiltration along the 220-km international border in the Jammu region as well as 720 km of the Line of Control (LoC) that divides Kashmir between India and Pakistan. The BSF guards the border while the army is deployed along the LoC.

The security around the post under fire has been increased, and checkpoints erected at various points leading to this city. 'We cannot rule out the possibility of militants having infiltrated. There are reports of militants stepping up infiltration and planning strikes around the festival season,' said a senior police officer in Jammu.

The Muslim festival of Eid-ul-Fitr is on Monday while the Hindu festival of Navratra starts Saturday. Both bring thousands of people out on the streets.

Senior BSF and police officials have been camping in the Nikowal area since Thursday evening.
