NATO: 6 US troops killed in Afghanistan

KABUL, Afghanistan — Six US service members and at least a dozen civilians died in attacks Saturday in Afghanistan's volatile east and south, adding to a summer of escalating violence as Taliban militants push back against stepped-up operations by international and Afghan forces.
On Saturday, two US troops died in the south in separate roadside bombings.
Other American service members died in the east: One as a result of small-arms fire, another by a roadside bomb, a third during an insurgent attack, and the last in an accidental explosion.
Their deaths raised to 23 the number of American troops killed so far this month.
Also, unknown gunmen killed 11 Pakistani Shia tribesmen in the east and at least one person died when a bomb planted on a motorbike exploded in Kandahar city in the south, officials said.
