French withdrawal from Afghanistan up to Paris: US The Pentagon said Friday it was up to France alone to decide whether to accelerate the withdrawal of French troops from Afghanistan after four of them were killed by an Afghan soldier. France's President Nicolas Sarkozy said he was considering an accelerated withdrawal of the French contingent following the incident, in which the Afghan soldier opened fired on the French, who were unarmed, during a sports session. Besides the four soldiers who were killed, another 15 were wounded in the attack. "We mourn for their losses today, but those are decisions that only the French government and the French people can make," Navy Captain John Kirby, a Pentagon spokesman, said of Sarkozy's remarks. "Their contributions are theirs to determine and theirs to amend as they see fit," Kirby said, calling the French "great allies and great friends." France has about 3,700 troops in Afghanistan, mainly in the provinces of Kabul and Kapisa, the scene of Friday's shooting. They are currently scheduled to be withdrawn by the end of 2013. "The French army stands alongside its allies but we cannot accept that a single one of our soldiers be wounded or killed by our allies, it's unacceptable," Sarkozy said. "If security conditions are not clearly established, then the question of an early return of the French army will be asked," he said.
