LIVE BLOG: The battle for Mosul - update 18th October 2016

Turkey's air force has been involved in coalition air strikes on the Iraqi city of Mosul, part of the US-backed operation to flush out Islamic State, Prime Minister Binali Yildirim said on Tuesday.

Turkey has been locked in a row with Baghdad about the presence of its troops at the Bashiqa camp in northern Iraq and over who should take part in the US-backed assault on Mosul. Turkey has trained up to 3,000 forces taking part but is concerned the operation could stoke sectarian tensions.
