Four US marines die in Afghan bomb blasts as offensive continues
The four marines died on Saturday in Helmand province, where about 4,000 troops this month launched the largest marine operation in Afghanistan since 2001. US forces have met little resistance but face the danger of roadside bombs everywhere they travel.
A fifth US service member wounded in June died of wounds in the US on Friday, said Lt Cmdr Christine Sidenstricker, who confirmed the deaths of the four marines.
