The U.S. military says Afghan police killed a senior militant commander this week in the central province of Ghazni.
A military statement says Abdul Baki was killed Wednesday while police were conducting a search of his residence.
The statement says Baki was the top militant commander in Ghazni's Andar district, leading a cell of 20 to 30 fighters who coordinated and carried out attacks on troops and government officials.
The statement says Baki attacked Afghan police with small-arms fire as they entered his residence.
The military says Afghan police discovered 50 voter registration cards in the compound. Authorities believe the cards were taken from villagers in order to prevent them from voting in the planned August presidential elections.
In a separate incident in Ghazni Wednesday, the U.S. military said seven militants were killed during an operation to cut the flow of weapons and fighters into eastern Afghanistan.
