Up to 12 civilians - 10 children and two women - are reported to have been killed in a Nato air strike in eastern Afghanistan.
At least one woman was reportedly killed and a further six are believed to have been injured in the incident in Shigal district, Kunar province.
Nato confirmed that "fire support" was used in Shigal after a US civilian adviser died in a militant attack, but said it had no reports of deaths.
Afghan President Hamid Karzai has condemned the killings.
