An eight-month-old child lost his life after he was hit by a stray bullet during ceasefire violation by Pakistan in Keri Battal area of Akhnoor near LOC.
The ceasefire violation comes two days after Pakistani forces were forced to "plead for ceasefire" after Indian troops retaliated forcefully to heavy shelling and firing from across the border. On Sunday, Pakistan Rangers called up the BSF unit in Jammu and requested for a ceasefire, a senior officer of the BSF said.
The BSF also released a 19-second thermal-imagery footage, showing the destruction of a Pakistani picket across the border, in retaliation to the unprovoked firing and shelling along the International Border.
The state has witnessed a spurt in Pakistani shelling and firing along the International Border and the Line of Control (LoC) this year. Over 700 such incidents have already been reported this year, which have left 38 people, including 18 security personnel, dead and dozens injured.
