MOSCOW, Dec 20 - Russian President Vladimir Putin's special envoy, Kirill Dmitriev, is heading to Miami for a meeting with U.S. President Donald Trump's envoy Steve Witkoff and his son-in-law Jared Kushner, a Russian source told Reuters.

The meeting in Miami takes place after talks in Berlin with Ukrainian and European officials held by Witkoff and Kushner earlier this week to try to reach a deal to end Russia's war in Ukraine. The duo were also scheduled to meet Ukrainian negotiator Rustem Umerov in Miami on Friday.
