WATCH: Turkey's border town of Kilis is struggling to cope with more than 100,000 refugees from Syria. Authorities have now closed the border to everyone except seriously ill or injured people. Shahida Yakub, a correspondent for RFE/RL's Current Time program, sent this report from the border, where many desperate Syrians are trying to escape from ongoing violence.
Turkish President Recep Tayyip Erdogan has warned Russia that its military actions in Syria are endangering its economic interests in Turkey.
"Losing Turkey would be a serious loss for Russia," Erdogan was quoted as saying on October 8.
He said Ankara could look elsewhere for gas supplies and cancel the construction of its first nuclear power plant, which is being built by Russia.
Russia is Turkey’s main gas supplier and analysts say that breaking Turkish dependence on Russian energy supplies was a near impossible task.
The comments come amid tensions with Moscow over Turkish airspace violations by Russian warplanes and Russia's air campaign in Syria to prop up the regime of President Bashar al-Assad.
In Moscow, Kremlin spokesman Dmitry Peskov expressed optimism that Moscow-Ankara cooperation could continue, saying it is “genuinely mutually beneficial.”
