KABUL — Two roadside bombs that struck back to back and only miles apart hit two U.S. military vehicles Monday, killing four American troops, U.S. and Afghan officials said.
U.S. military officials have predicted a 50 percent spike in roadside blasts in Afghanistan this year as militants step up attacks and thousands more troops pour into the country.
The deaths bring to 64 the number of U.S. forces killed in Afghanistan this year, according to an Associated Press count based on military figures.
