The Kremlin said on Tuesday that it respects what it calls Turkey's "legitimate" security concerns over Syria but said all parties there should avoid steps that could worsen the situation.
Turkey launched air strikes on Kurdish militant bases in northern Syria and Iraq on Sunday and President Tayyip Erdogan has said it may deploy ground forces as it targets groups it blames for a bombing in Istanbul on Nov. 13.
Kremlin spokesman Dmitry Peskov told reporters that while there were disagreements between Russia and Turkey in their approach to Syria, Moscow understood Turkey's security concerns.
