The Inter-Services Public Relations (ISPR), the media wing of Pakistan army, said that the personnel of Frontier Constabulary, a paramilitary force, came under attack from the Afghanistan side when they were carrying out a routine surveillance at the Pak-Afghan border in Kurram Agency, the country's northwest tribal region. Pakistani troops are exercising maximum restraint so as to avoid any Afghan civilian casualties.
Afghan and Pakistani troops clashed near the disputed border between the two countries on Sunday. Announcements were made through loudspeakers in mosques, asking the Turi Bangash and other tribesmen to move to the border areas.
Police Chief in Khost Abdul Hanan confirmed that one security man was killed in the firing.
According to foreign news agencies, the casualties were the result of ongoing clashes along the border between Afghanistan and Pakistan.
Afghanistan has refused to recognise the Durand Line - a 2,400-kilometre frontier drawn by the British in 1896 - as it splits the Pashtun ethnic group between the nations.
The ISPR statement further said that the officials were reviewing fencing arrangements on the border when the incident occurred. He added that local villagers and the Afghan Border Police retaliated with gunfire.
Mangal said three Pakistani guards were also taken into custody. Clashes are still underway, Col Hanan said. A local political official, who asked not to be identified, said that Pakistani security forces had responded on Sunday by opening fire along the border.
Earlier this month, Afghanistan accused Pakistan of carrying out air strikes in its Kunar province, causing "massive property damage" - charges Islamabad vehemently denied. It was once an ideal point for militants to move across the border in the past.

Russian Federation and its ally Syria called the attack fabricated and said no evidence of chemical weapons use exists in Douma. Smoke could be seen rising from the northern and eastern edges of the capital.
