Russian President Vladimir Putin said Tuesday that peace talks with Ukraine had reached “a dead end,” an ominous sign as the country pushes ahead with its military offensive.

Putin claimed Kyiv negotiated in bad faith, saying Ukraine changed its position on several points after negotiators from both sides met for peace talks in Turkey on March 29. Negotiations are “back to the dead-end solution,” and the fighting “will continue to its complete end,” the Russian leader said.
