France on Friday threatened to pull all of its troops out of Afghanistan early after an Afghan soldier killed four French NATO personnel on the same day. France had been conducting training operations for Afghan troops, but they have now been suspended. President Nicolas Sarkozy confirmed the deaths, which brings to 82 the number of French troops killed in the war in Afghanistan. “The French army is not in Afghanistan so that Afghan soldiers can shoot at them," Sarkozy said. Afghan President Hamid Karzai is expected to meet with Sarkozy in Paris next week. Six NATO soldiers were killed in a separate helicopter crash early Friday, with early signs indicating all six were Americans.
