At a news conference Sunday, Karzai spokesman Amal Faizi sought to clarify the president’s statement, saying the abuse allegations were connected to Afghans working “within these special forces groups.”
“Those Afghans in these armed groups who are working with the U.S. Special Forces, the defense minister asked for an explanation of who they are,” Faizi said. “Those individuals should be handed over to the Afghan side so that we can further investigate.”
It was not immediately clear which Afghan units were involved in the alleged incidents.
The gradual withdrawal of U.S. and NATO troops and mild winter weather have allowed insurgents to be more active in various parts of Afghanistan than in past years.
On Sunday, Taliban suicide bombers targeted Afghan security forces in three separate attacks.
One of the attacks targeted a building used by the country’s main intelligence agency, the National Directorate of Security, in the eastern city of Jalalabad, Afghan officials said. Two intelligence agency guards died when a bomber exploded a vehicle near the building, they said.
Hours later, a second bomber tried to storm a police post in Logar province, south of Kabul. Police fatally shot the bomber, but he was able to detonate his explosives, killing one officer.
In an evidently coordinated attack in Logar, a suicide attacker set off his bomb near a group of police officers, killing one and a civilian, authorities said.
The Taliban asserted responsibility for the attacks in Jalalabad and Logar province.
In Kabul, security forces killed a man inside a sport-utility vehicle. They suspected the man was planning to stage an attack in front of a branch of the intelligence directorate in an area where several Western embassies are based.
