Turkey's prime minister says the international community never had a plan to end the intensifying Syrian conflict.

Ahmet Davutoglu also told a news conference Thursday that all countries should fight the Islamic State group but also keep the Syrian regime from committing "war crimes" in Aleppo, Syria's largest city. He warned that if the attacks in Aleppo continue, "there may be hundreds of thousands of refugees approaching to Turkey."

He said the plan for a freeze in fighting in Aleppo proposed by U.N. envoy Staffan de Mistura was good but the Syrian government wasn't keeping its promises.
