The Polish Consulate was hit by a projectile in Lutsk, western Ukraine, Wednesday, damaging the roof of the consulate and shattering the windows. Poland’s consul in Ukraine, Krzysztof Sawicki, asserted that the attack may have come from a grenade launcher.
Krzysztof Sawicki, Poland’s Consul (Ukrainian): “The shell hit the Consulate’s building after midnight, concretely to its roof, 20-30 centimeters above the window of the office apartment where the employee of the Consulate was sleeping. Thank God that nobody was killed.”

THE Polish consulate in the Ukrainian city of Lutsk was hit by an anti-tank rocket overnight in what the consul called a “terrorist attack.”
A hole was blown in the building’s roof above a room where a member of staff was sleeping.
Police found part of a RPG-22 disposable rocket launcher nearby, and said the rocket was fired from a nearby backyard.
Lutsk, the capital of Volyn province northeast of Lvov, is in the western hotbed of far-right Ukrainian nationalism that glorifies WWII nazi collaborators who massacred up to 100,000 Poles in the region.
