Polish officials were among many who sent condolences to Ukraine after a helicopter had crashed in Brovary, near Kyiv, killing at least 18 people including Ukraine's Interior Minister Denys Monastyrskyi. "My thoughts are with the families and loved ones of the victims," said Poland's President Andrzej Duda. PM Mateusz Morawiecki, Interior Minister Mariusz Kamiński, Foreign Minister Zbigniew Rau, National Security Bureau chief Jacek Siewiera, as well as fire service and police chiefs, all extended their sympathies to the Ukrainians.
