A soldier was killed in indiscriminate firing by Pakistani troops in Krishna Ghati sector in Jammu and Kashmir's Poonch district on Sunday night.
The unprovoked firing appears to have escalated tension along the border ahead of United States President Barack Obama's visit to India.
According to official sources, Pakistani troops targeted the Indian posts of Kirpan, Kranti and Kirpan-II from their forward posts of Chuha and Daaku.
The army is already aware of Pakistan's plot to create tension along the Line of Control as well as the International Border before and during Obama's visit.
According to defence sources, the movement of militants has not been observed and intrusion bids, if any, have been thwarted.
The army and the Border Security Force is maintaining a high alert along the Line of Control to thwart infiltration attempts by the militants.
