(AP Photo/Maya Alleruzzo, File) (Newser) – Two US troops were killed today by an Iraqi soldier who apparently smuggled real bullets into a training exercise and opened fire. A US military official said the shooter was immediately killed by American soldiers who were running the morning drill at a training center on a base in the northern city of Mosul. The official said the exercise was not meant to involve live ammunition, and an Iraqi army officer said the shooting appeared to have been planned. The attacks raises fresh concerns about insurgents worming into the nation's security forces as the Americans prepare to leave by the year's end. Additionally, another American soldier was killed during an unrelated military operation in central Iraq, making it one of the deadliest days for US forces in the country in months. A military statement offered no details about that death.
