This report is unconfirmed at this time. Due to the ongoing conflict in eastern Ukraine, it would be highly unlikely for Russian President Vladimir Putin to make an unannounced visit to the city of Mariupol in the Donetsk region.
The region is currently occupied by pro-Russian separatists, who are backed by the Russian government. In the past, Putin has made several high-profile trips to Ukraine, but these have typically been more formal events, such as his visit to Kiev in 2017. Furthermore, it is unlikely that Putin would risk travelling to an area that is still the subject of an armed conflict, and so it is highly doubtful that such a visit has taken place.
