MOSCOW (AP) — Russian President Vladimir Putin hosted his Turkish counterpart Recep Tayyip Erdogan for talks Wednesday in the Black Sea resort of Sochi that were expected to focus on war-torn Syria. As the two leaders sat down for talks, Putin pointed out that relations between the two countries “develop positively.”“Negotiations are sometimes difficult, but with a positive final result. The talks between the two presidents come amid an increase in airstrikes on Turkey-backed opposition fighters’ positions in northern Syria, especially in the province of Idlib. For its part, Russia accuses Turkey of failing to take measures to push out radical groups from northern Syria. The talks between Putin and Erdogan on Wednesday lasted for about three hours, Russia’s state news agency Tass reported.
