Protestors said they dumped two tons of dung outside the home of the Russian ambassador to Poland on Saturday, as they marked the second anniversary of the full-scale invasion of Ukraine.

Activists put a bloodied Russian flag with the letter "Z" on the pile of manure and stuck a sign into it that said "Russia = shit! We don't want you in EU! Get out!," pictures of the protest in Konstancin-Jeziorna, seen by Reuters, showed. The town near Warsaw is where the ambassador lives.

Elsewhere in Warsaw at 6 a.m. local time other protestors played the sound of sirens, gunfire and explosions outside a building housing Russian diplomats.

"We wanted a clear signal to the Polish authorities and the European Union. It's high time to expel Russian diplomats from our country," said Dominik, a protestor quoted in a statement.

The Russian embassy in Warsaw did not immediately respond to an emailed request for comment.

In contrast to the Baltic states which have expelled Russian ambassadors, Poland has so far not taken such a step although it has removed diplomats.

Russia’s invasion of Ukraine started the deadliest war on European soil in more than 70 years.
