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.

Russian and Ukrainian delegates met in Istanbul on Monday for their second set of direct peace talks, a day after Kyiv launched a shock drone attack on Russia’s nuclear-capable bombers, in an operation that President Volodymyr Zelensky said was a year and a half in the making.

Expectations were low for any breakthrough on ending the 3-year-old war after a string of stunning attacks over the weekend.
