Turkish premier Ahmet Davutoglu will meet the main opposition leader Thursday for decisive talks that will likely determine if the country forges a coalition government or heads to snap polls, AFP reports.

Turkey has been without a full time government since the ruling Justice and Development Party (AKP) lost its overall majority in June 7 legislative elections for the first time since taking power in 2002.

The political impasse comes as Ankara wages one of its biggest security operations in years - a cross-border offensive against "Islamic State" (ISIS) terrorists in Syria, and an offensive targeting Kurdistan Workers Party (PKK) rebels in northern Iraq and southeast Turkey.
