More than a decade after the U.S. charged into Afghanistan, American troops are still in the lead combat role. But with the U.S. military planning to withdraw by the end of 2014, the Americans now want to see Afghan troops at the forefront of the fighting.

France is suspending training operations in Afghanistan and threatening to withdraw its entire force from the country early after an Afghan soldier killed four French troops Friday. The French foreign minister described the attack as an "assassination."

Four French troops were killed today by a member of the Afghan National Army. The New York Times says there have been dozens of such attacks since 2007. Also today, six U.S. Marines died in a helicopter crash. The cause of the crash isn't known.

NATO said in a statement early Friday morning that there was no enemy activity in the area at the time of the crash in southern Afghanistan. A military official said all six dead were Americans. The cause of the crash is being investigated.

The Taliban has announced it is setting up an office in the Gulf state of Qatar as part of a process that might lead to peace talks in Afghanistan. Michael Semple, a fellow at the Carr Center for Human Rights Policy at Harvard's Kennedy School, talks to Renee Montagne about an article he's written for Foreign Affairs magazine called "How to Talk to the Taliban."
