SIALKOT Pakistan has expressed grave concern over the ceasefire violation by the Indian security forces during which Pakistani border villages were targeted along the Working Boundary in the Zafarwal Sector, official sources said. Earlier, indiscriminate firing and shelling by the Indian security forces created panic among the locals. According to the official sources, the Indian security forces started sudden firing and shelling on late Monday night (the night between Monday and Tuesday) from Kamore Post at Ramgarh Sector located in the neighbouring Occupied Jammu and Kashmir. The sources said the Indian security forces used Wikras and G-2 guns. The Chenab Rangers retaliated the fire and gave a befitting answer to the Indians border guards. However, no loss of property and casualty was reported.
