"The Special Operations Forces arrested four Haqqani network members in Khost. They also seized some amount of weapons and ammunition during the raid," the Afghan National Army Special Operations Corps said in a statement.
The statement said the raid was conducted after a credible intelligence report indicated the presence of the militants in a village and no gunshot occurred during the operation in the province, 150 km southeast of Kabul.
As a Taliban-linked group, the Haqqani network is mostly operating in eastern provinces and capital Kabul, and has been responsible for many high-profile attacks against security forces.
The network, which was designated as a terrorist group by the United States in 2012, has yet to make comments.
