Russia's President Vladimir Putin says his country is ready to resume peace talks with Ukraine. Both sides continue to target each other - Ukraine says it struck four warplanes in its most recent attack on Russia's war assets.

President Vladimir Putin said on Friday that Russia was ready to hold a new round of peace negotiations with Ukraine, potentially in Istanbul, although the time and venue had yet to be agreed. Putin said there were big differences between the proposals submitted by the two sides at previous talks but expressed hope that continued dialogue would help narrow the gap.

Russia and Ukraine exchanged more long-range drone attacks that have become a staple of the more than three-year war, officials said Friday, as Russian President Vladimir Putin said Moscow is ready for a fresh round of direct peace talks in Istanbul.
