European Commission President Ursula von der Leyen arrived in Kiev today to mark Europe Day and show support for Ukraine in the face of Russian aggression on the day Moscow commemorates victory over Nazi Germany.

Ursula von der Leyen arrived in Kiev on an overnight train from Poland to meet Ukrainian President Volodymyr Zelensky and work on Ukraine’s bid to join the European Union, according to reporters accompanying her.

Shortly before her arrival, air raid sirens sounded for two hours in Kiev.

Yesterday, Monday, the Ukrainian president signed a decree to celebrate May 9 as Europe Day in his country, as is done in Brussels. He thus canceled any event for the victory over Nazi Germany on May 9, as is done in the Soviet tradition in force in Russia, which organizes a large military parade in Red Square on this day.

“I warmly welcome President Zelensky’s decision to make May 9 Europe Day. Ukraine is part of our European family,” von der Leyen told reporters accompanying her on the train to Kiev.

“My presence in Kyiv today, May 9, is symbolic, but it is also an indication of a critical and very practical reality: the EU is working hand in hand with Ukraine on numerous issues.”
