#Reuters: "Russia's demands in talks are unrealistic"

A Ukrainian diplomatic source told Reuters that Russia's demands in the talks are unrealistic and go beyond the scope of previously discussed points.

The Russian delegation in Istanbul is demanding that Ukraine withdraw its troops from its territory to ensure a ceasefire, adding that Russia's demands also include other "unacceptable conditions," the outlet reported.

Direct Russian-Ukrainian talks are still underway in Istanbul.

Turkish intelligence chief Ibrahim Kalin has also joined the negotiators.
