At least 3,188 Afghan civilians have been killed in the war with the Taliban in 2014, making it the deadliest year on record for non-combatants, the United Nations said Friday. "The situation for civilians in Afghanistan is becoming increasingly dire," said Georgette Gagnon, the human-rights director for the U.N. mission in Kabul. "That is very worrying," Gagnon said, calling on all sides to do more to keep civilians from being caught in battles.
