Vice President Joe Biden spoke with Turkish Prime Minister Ahmet Davutoğlu on Saturday about the countries' shared goal of stopping the Islamic State in Syria, Agence France-Presse reports.
On the ongoing attempt at a political resolution to Syria's five-year civil war, Biden said: "We are neither optimistic nor pessimistic. We are determined." Biden went onto suggest a "military solution" for Syria is on the table, should political means fail.
Biden also condemned Turkey's Kurdistan Workers Party as a terrorist group, likening their actions to those of ISIS.
