RAWALPINDI: Five Pakistani civilians sustained injuries on Thursday as Indian and Pakistani troops exchanged fire across the Working Boundary, the Inter-Services Public Relations (ISPR) said. The “intense and heavy” exchange of fire continued for 11 hours on Harpal and Chaprar sectors on the Working Boundary, it said. The ISPR added that Pakistani troops responded “befittingly” to Indian firing and inflicted “heavy casualties” while targeting Indian posts. Heavy mortar shelling by the Indian Border Security Force (BSF) on villages along the Working Boundary a day earlier killed two residents of villages in the Chaprar sector and left another eight badly wounded. In total, more than four people, including an infant, have been killed and 26 residents of villages along the Working Boundary have been injured since Monday. For the third time in less than two weeks, the Indian deputy high commissioner was summoned to the Foreign Office where the South Asia and Saarc director general lodged a protest over ceasefire violations by the BSF in the Chaprar and Harpal sectors and along the Line of Control in the Bhimber sector. The Indian diplomat was asked to ensure that the incidents were investigated and that the findings shared with Pakistan.
