What is Turkish army really doing in Iraq?
It is not clear who will take control if Mosul is liberated from the Islamic State, but Turkey and its allies want nothing more than to prevent the Kurds from declaring a semi-autonomous state in the region.
A cannon shot roared into the night. The target was in the town of Bashiqa in northern Iraq, seized by the Islamic State (IS) in 2014. Seconds after the explosion, the clatter of a collapsing building echoed in the mountain.
For months now, the Turkish army has repeatedly targeted IS from positions they hold 15 kilometers (9 miles) northeast of Mosul.
