【答案解析】[听力原文]
On the second day of a major offensive against the Taliban in the southern Afghan province of Helmand, NATO-led forces have killed 12 civilians by mistake. A NATO statement said two rockets veered off target.
According to military officials, the two rockets were supposed to target insurgents who they say were firing from a compound. But the weapons missed their target by 300 meters, killing the civilians in Marjah. In a statement, [6]NATO-led forces say they've suspended the use of this particular rocket while they investigate. Despite the deaths, commanders say the operation is proceeding as planned. Progress, however, has been slow in Marjah town as forces clear homemade bombs and booby traps from roads and compounds.
背景NATO的全称是North Atlantic Treaty Organization, 即北大西洋公约组织，简称北约，是美国与西欧、北美主要发达国家为实现防卫协作而建立的一个国际军事集团组织。
[解析]C项“他们从没误杀平民”在新闻中未提及，所以C为正确选项。
[点睛] 事实细节题。新闻中，NATO发表的声明中还提及在调查的过程中；他们已经暂停了这种火箭的使用，A与B陈述正确。指挥官称，尽管发生死亡事故，行动还是按原计划进行，D陈述正确。
