President of Ukraine Volodymyr Zelenskyy has published a tweet, offering his condolences to Poland on the 13th anniversary of the Smolensk Air Disaster which claimed the life of Poland's President Lech Kaczyński and 95 other passengers aboard the presidential plane.

"Today, on the 13th anniversary of the Smolensk disaster, we unite in grief with the Polish people and honour the memory of the President of Poland Lech Kaczyński, his wife, and all those who died in the name of serving the motherland. Eternal memory!" Zelenskyy wrote.

Dziś w 13. rocznicę katastrofy smoleńskiej łączymy się w smutku z Narodem Polskim i oddajemy hołd pamięci Prezydentowi RP śp. Lechowi Kaczyńskiemu, Jego Małżonce i wszystkim, którzy zginęli w imię służby Ojczyźnie. Wieczna pamięć!

Several commemorative events are being held in Poland to mark the tragic anniversary.

President Andrzej Duda and his wife have already laid flowers at the burial place of the Kaczyńskis and are on their way to the graves of other victims.

On April 10, 2010, the presidential plane carrying a delegation on its way to commemorate the 70th anniversary of the Katyn Massacre (the Polish authorities now want to recognise it as an act of genocide), crashed during a landing attempt at Smolensk Airport near Katyn. President Lech Kaczyński and his wife Maria, senior military commanders, and the last president of Poland in exile, Ryszard Kaczorowski, were aboard.
