NATO says seven American service members have died in two separate roadside bomb attacks in southern Afghanistan.
No details were given of Monday's attacks, although eyewitnesses in the southern city of Kandahar said an armored U.S. Army Humvee hit a roadside bomb in the early afternoon. Several bodies were seen being removed from the vehicle, which was on fire.
The deaths bring to 14 the number of U.S. troops killed in action in eastern and southern Afghanistan over the past three days.
A spike in U.S. troop numbers in Afghanistan to over 120,000 has brought increased fighting and a rising death toll. Forty-nine U.S. service members have died in Afghanistan this month.
