Armed clashes broke out on Thursday evening between Afghan and Pakistani border guards in the eastern Afghan province of Khost.

Mullah Bilal, security chief at the Ghulam Khan border crossing with Pakistan, told Afghan media that the clashes broke out in the evening hours of Thursday.

He added that the clashes continued until dawn on Friday, without giving details of the causes of the clashes or whether there were casualties on either side.

Governments in Afghanistan, including the current administration, reject the Durand Line, the official international demarcation of the border between the two countries, with checkpoints set up by the Afghan side on the border line emerging as a major point of contention between the two sides.
