Two US soldiers have been killed when an Iraqi soldier opened fire on them during a training exercise in northern Iraq, US and Iraqi officials say.
The officials - speaking on condition of anonymity - said the incident happened at al-Ghazlani training camp in the city of Mosul.
It was the final drill to showcase US efforts in training Iraqis before next week's visit by US and Iraqi generals.
The Iraqi soldier who opened fire was arrested, US military officials said.
Separately, a US soldier was killed in central Iraq.
