On Saturday, Warsaw mayor's office officials, accompanied by Polish police, arrived at the Russian embassy's school building and stormed the premises after breaking the door. The Russian Foreign Ministry pledged a "harsh reaction and consequences for the Polish authorities and Polish interests in Russia" in response to "such an insolent move." The same day, the ambassador said that a new building will be found to house the school so that the studies could continue.
"The Embassy has sent a protest note to the Polish Foreign Ministry," Russia's diplomatic mission in the country said.
