Islamic State militants fired rockets on Wednesday at a base in northern Iraq where Turkish troops are stationed, Kurdish military sources told Reuters.
The rocket fire was part of a broader offensive by the insurgents on Kurdish positions around the Islamic State stronghold of Mosul, according to Jabbar Yawar, the secretary general of the Kurdish peshmerga forces, and a general.
The general, who was near the base in the Bashiqa area, said six or seven rockets had landed inside it, hitting a part of the compound occupied by an Iraqi militia that Turkey says it is training to fight Islamic State.
The deployment of around 150 Turkish troops to the base earlier this month has strained relations between Ankara and Baghdad, which complained to the UN Security Council.
Baghdad says the Turkish military presence is a violation of its sovereignty.
Turkey withdrew some troops earlier this week and moved them to another base inside Iraq's Kurdistan region, but Baghdad said it should pull out completely.
