Russia has good ties with
Turkey but will sometimes disagree, Russia's Foreign Minister Sergei Lavrov said on Saturday.
Turkey is purchasing a
Russian S-400
missile defense system in defiance of its NATO allies but the two countries support opposing sides in Libya.
The fighting in northwestern
Syria has led to testy exchanges between
Russia, which supports an offensive by Syrian troops, and Turkey which has deployed its own soldiers to support insurgents trying to halt the advance.
