From NBC's Jim Miklaszewski
U.S. military officials tell NBC News that eight Americans and one Afghan civilian translator were killed in two separate "complex" IED attacks on U.S. military patrols in southern Afghanistan.
Seven Americans and the translator were killed when their patrol struck a roadside bomb, and then they were immediately attacked with RPGs and small arms fire by enemy forces.
One American was killed in a similar attack on a U.S. patrol in a separate area in the south part of the country.
The two incidents came "a couple of hours apart." The U.S. military is withholding the exact locations and the Americans service affiliation pending notification of next of kin.
