Poland's prime minister arrives in Ukrainian capital Kyiv

Polish Prime Minister Donald Tusk arrived in Ukraine on January 22, his office said, in a show of support as the war with Russia nears the two-year mark.

Warsaw has emerged as a key ally for Kyiv as it defends itself against Russia and seeks more financial and military support from Western partners, Reuters reports.

A video released by Tusk's office shows the newly installed leader, who assumed office last month, arriving at Kyiv's main train station.

Tusk's visit coincides with Ukraine's Unity Day holiday.
