ISTANBUL (Reuters) - Turkey remains committed to a ceasefire in Syria, but Russia must stop insisting that Bashar al-Assad should remain as leader of the country, Ankara’s foreign minister said on Sunday.

Mevlut Cavusoglu, in live comments on state broadcaster TRT Haber, also said that he told his Russian counterpart that Moscow did not take the necessary steps in the face of breaches in the Syrian ceasefire.
