Six U.S Soldiers Killed in Afghanistan

The soldiers were killed by a civilian employee in two separate attacks.

Two separate gun attacks on Nato-led troops in south Afghanistan have left a total of six US soldiers dead, coalition officials say.

An Afghan civilian employee shot three soldiers, all from the US, at a base in Helmand province on Friday evening.

Earlier on the same day, also in Helmand, an Afghan police officer shot three US marines after inviting them to dinner at a checkpoint.
