Afghanistan is facing what is being described as its deadliest period for civilians since the U.S.-led invasion began more than nine years ago. According to Afghan officials, more than 200 Afghans have been killed in attacks and military operations of the past two weeks. An Afghan government panel is still investigating claims some 65 people were killed in a U.S.-led attack last week. On Saturday, a government adviser and investigator said that 40 of the dead were children.
