An air strike by US-led forces has killed four policemen and two civilians in eastern Afghanistan, officials say.
The air strike occurred yesterday as Nato troops and Taliban militants were fighting about six miles away from an Afghan police checkpoint in the Deh Yak district of Ghazni province, an Afghan official said.
District chief Fazel Ahmad Toolwak says the two civilians killed were brothers who were in a car that was being searched by police at the checkpoint.
The coalition says it is looking into the report.
The air strike followed a suicide attack by insurgents wearing Afghan army uniforms who stormed a courthouse in a failed bid to free Taliban inmates, killing at least 44 people.
Nine attackers died in the incident, which raised fears of deteriorating security as international combat forces withdraw by the end of 2014 and hand over control to Afghan security forces.
The attack began when nine men wearing suicide vests drove into the capital of Farah province in western Afghanistan, evading checkpoints by using army vehicles, according to the provincial police chief.
The stand-off ended some eight hours later when the last gunman was killed.
