Afghan officials said Sunday that 26 militants were killed in a gun battle with border security guards along the Pakistan frontier. NATO also reported that an Afghan woman was killed when she was struck by an international forces vehicle in Kabul.

The Ministry of Interior said Sunday that the battle between militants and the border guards occurred Saturday night in the Gurbuz district of Khost province in eastern Afghanistan.

The ministry says the bodies of 13 militants were recovered following the fighting. Air support was summoned to the area. No Afghan border security guards were killed in the violence, according to the ministry.

In the pedestrian accident, the driver of the NATO vehicle stopped after hitting the woman and transported her and her son to a medical facility at the Kabul International Airport compound. Despite medical treatment, the woman died of severe trauma.

"This is a very tragic accident," Navy Capt. Jane Campbell, a NATO spokeswoman, said. "Our thoughts and prayers are with her family at this difficult time."

The incident is being investigated by NATO and local police.

Separately, NATO reported that German Brig. Gen. Jurgen Setzer, commander of a NATO regional command in northern Afghanistan, is returning to Germany for medical treatment. German Brig. Gen. Frank Leidenberger will replace Setzer. No other details were released.
