Kabul, June 30: US-led forces have killed at least five private security contractors and injured nine others in an airstrike in the troubled eastern Afghanistan.
The strike took place on a NATO logistics convoy in Sayedabad district of Wardak province, a Press TV correspondent reported on Thursday.
The US led forces reportedly hit the convoy after it was attacked by militants.
NATO officials claim they have only killed militants in the air strike.
In a separate development, a roadside bomb has killed six civilians in southern Helmand province. Afghan officials say four children are among the dead.
All the victims were members of a family in a vehicle that was hit by the blast.
No group has claimed responsibility for the attack.
Civilian casualties by US-led foreign forces have been a major source of friction between Kabul and Washington.
Hundreds of civilians have lost their lives in the US-led airstrikes and ground operations in various parts of Afghanistan over the past few months, with Afghans growing frustrated over the seemingly endless number of deadly assaults.
Afghan authorities have repeatedly warned NATO forces to avoid killing civilians during military operations.
The attacks have left a large number of Afghan civilians dead since the start of the US-led invasion in 2001.
The war in Afghanistan, with civilian and military casualties at record highs, has become the longest war in US history.
