Two Afghan border guards opened fire on NATO Resolute Support mission advisors at the military base in Herat province in western Afghanistan, according to reports.

An Afghan service member was killed and another wounded, Noorullah Qaderi, Commander of the 207 Zafar Military Corps told Pajwok.

The Resolute Support members were visiting the Fifth Border Security Forces battalion in Islam Qala, a town at the Afghanistan-Iran border.

None of the foreign troops, who were traveling in a vehicle at the base, were injured. One of the attackers was killed and another taken into custody, Tolo News reported Qaderi as saying.

“Today, an insurgent acting as a member of the Afghan security forces fired on Coalition members, the Coalition members returned fire and killed the attacker. No Coalition members were injured in the attack,” Resolute Support told The Defense Post in an emailed statement.

On October 22, a Czech service member with the NATO mission in Afghanistan was killed in an insider attack at the Shindand airbase in Herat. It was the second “green on blue” attack in Afghanistan in less than week. Four days earlier, a bodyguard for Kandahar governor Zalmay Wesa opened fire on Afghan and U.S. officials following a high-level security meeting.

Kandahar police chief General Abdul Raziq and National Security Directorate provincial chief Abdulmomin Hassankhail were killed. Wesa and U.S. Army Brigadier General Jeffrey Smiley were injured.

General Scott Miller, the top U.S. and NATO commander in Afghanistan, attended the meeting but was not injured.
