By Daren Butler and Isabel Coles ISTANBUL/ERBIL (Reuters) - Turkey said on Monday it had a duty to protect its soldiers around the Islamic State-controlled city of Mosul in Iraq and that they were there simply on a training mission, after Baghdad ordered the immediate withdrawal of its latest deployment. Turkey sent hundreds of forces to a camp in the Bashiqa region of northern Iraq on Thursday. It described it as a routine rotation in an existing training program to help Iraqis retake Mosul from Islamic State, and said the troops were there to ensure the safety of the Turkish military trainers.
