Pakistani and Indian border guards traded gunfire and mortar shells along their disputed border in the Himalayan region of Kashmir on Tuesday, killing two Pakistanis and an Indian villager, officials said. Six civilians also were wounded by Indian fire in the Bajwat sector near Sialkot, a city in the eastern Punjab province, Pakistan’s military said in a statement. It said Pakistani troops responded to the “unprovoked” Indian fire and that the exchange of fire continued into Tuesday afternoon. Indian Inspector-General Danish Rana blamed Pakistan for firing first, saying an Indian villager was killed when Pakistani troops shot at a dozen Indian border posts in the Jammu region. An official with India’s border security force said the Pakistani fire also wounded four civilians. He said the Pakistani troops opened fire first and the Indian troops “retaliated.” The official spoke on condition of anonymity because he was not authorized to talk to journalists.
