Report states U.S, Nato airstrikes in Afghanistan have tripled

(CNN)– A report issued by Human Rights Watch reveals that U.S and NATO airstrikes in Afghanistan have tripled between 2006 and 2007.  The report is a result of a U.S. military investigation on the August 22nd airstrike, which Afghanistan officials say killed 90 civilians, contradicting U.S military reports that the strike killed five to seven civilians.
