Poland announced Friday that it has provided Ukraine with its first Leopard tanks to aid the fight against Russia.

"The Leopard tanks will definitely stand up well in your formation on the battlefield. They will work great," Polish Prime Minister Mateusz Morawiecki told Ukrainian President Volodymyr Zelenskyy during a visit to Kyiv to mark the one-year anniversary of Russia's full-scale invasion.

Poland delivered four Leopard 2A4s -- a model of the latest version of the German main battle tank -- to Ukraine, with more expected to be on the way, according to Morawiecki.

"We will also soon hand over more and we urge our partners from the European Union and NATO to do the same," Morawiecki said.
