A Polish consulate in Lutsk, western Ukraine, was shot at in the early hours of Wednesday, authorities say, adding that no one was injured.

“It was probably a grenade launcher. The projectile hit the top floor, leaving a hole of about 70 cm,” Consul Krzysztof Sawicki told the PAP news agency.

The incident took place half an hour after midnight local time (23.30 pm CET on Tuesday). At that time, the only people at the consulate were security guards.

No one was injured as a result of the attack.

The Polish foreign ministry has called in the Ukrainian ambassador to Poland in relation to the attack.

“At this moment we expect and demand that the security of our institutions be expanded across Ukraine,” a spokesman for the Polish ministry said.

He added that Poland is requesting the circumstances of the incident to be clarified as soon as possible, as well as the “detention of the perpetrator or perpetrators”.

Tuesday's incident follows a series of attacks against Polish monuments in western Ukraine.

In January a monument to the Poles murdered in 1944 in the village of Huta Pieniacka in Ukraine was destroyed.

In a separate incident days later, another site at the Bykivnia cemetery in western Ukraine was painted over by vandals. Both sites were dedicated to the memory of Poles who were killed in WWII.
