Afghan troops clashed with Pakistani forces near the disputed border on Sunday, in fighting that killed two Pakistani paramilitaries and wounded five others, officials said.
The ISPR added that the security personnel were plugging the gaps at the border and making necessary preparations to start fencing in that area to stop unwanted infiltration from the Afghanistan side.
The attack was carried out from the Khost province of Afghanistan on a border post in Laka Tika area of Lower Kurram Agency, officials of the political administration in Kurram Agency said. It said the paramilitaries showed "maximum restraint" to avoid civilian casualties, and that "military engagement" is underway to defuse the situation. Mosques in Pakistan's Kurram Agency region, where the attack took place, made announcements urging locals to assist the armed forces, prompting throngs of armed civilians to arrive at the border after the attack.
Two Pakistani soldiers were killed in cross-border fire from Afghanistan while working on a fence meant to cover almost all of the disputed 2,500km border separating the countries, the Pakistani military said on Sunday.More news: The Answer Trump Needs in Syria
