Turkey says investigating reports 28 truck drivers kidnapped in Iraq
Turkish media reports said the drivers were being held hostage after being seized while carrying diesel from Turkey's southern port of Iskenderun to a power plant in Mosul.
Insurgents overran the headquarters of the provincial government in Mosul late on Monday, making further gains in a fourth day of fighting in the country's second-largest city.
