Ukrainian President Volodymyr Zelensky said on Saturday that Russia had adopted a "fundamentally different approach" in talks to end the conflict, AFP reported.

In a media briefing, Zelensky said that the approach was in contrast to earlier talks at which Moscow only "issued ultimatums" and that he was "happy to have a signal from Russia" after President Vladimir Putin said he saw "some positive shifts" in their dialogue.

Putin indicated previously that negotiations are "now being held on an almost daily basis.”

Russian and Ukrainian negotiators have held several rounds of talks since Putin sent in troops to the country.

Turkey on Thursday hosted the first talks between the Russian and Ukrainian foreign ministers since the military operation.

The talks have led to the opening of several humanitarian corridors to evacuate civilians from combat areas. Both sides have accused each other of blocking these efforts.
