8 civilians killed in Afghanistan by alleged air strike

Afghan officials say that at least eight Afghan civilians, including four children, have been killed in an attack in western Farah province.
However there is disagreement over what exactly caused the deaths.
Mohammad Naser Mehri, spokesman for the provincial governor, said Saturday that the incident was a roadside bomb explosion. But family members of the victims are claiming they were hit by an air strike.
Gen. Dawlat Warizi, a Defense Ministry spokesman, told The Associated Press that an investigation of the incident is underway.
