Turkish President Recep Tayyip Erdogan spoke to Ukraine’s Volodymyr Zelenskiy by telephone, discussing the situation in Ukraine and negotiations between Moscow and Kyiv, Erdogan’s office said late Friday.

Erdogan told his counterpart that he had raised Turkey’s support for Ukrainian territorial integrity at a recent NATO summit, where he had relayed the diplomatic efforts made by Turkey in one-one-one meetings with other leaders, according to a statement from the Turkish presidency.

Ankara, which has close ties with both Russia and Ukraine, has positioned itself as a neutral party, seeking to facilitate negotiations between the warring sides.
