By Vladimir Soldatkin, Tom Balmforth and Huseyin HayatseverISTANBUL (Reuters) -Russia told Ukraine at peace talks on Monday that it would only agree to end the war if Kyiv gives up big new chunks of territory and accepts limits on the size of its army,

Ukraine suspects Russia is not really interested in pausing the conflict and ending the war, and the head of the country’s delegation, Defence Minister Rustem Umerov, said the key points could only be resolved at face-to-face talks between President Zelensky and President Putin.

Russia on Tuesday said it was wrong to expect a quick breakthrough in Ukraine talks, a day after Moscow rejected Kyiv's call for an unconditional ceasefire at negotiations in Istanbul.
