Poland announced on Saturday, April 29, that it had seized the building of the Russian high school in Warsaw. An act immediately qualified as "illegal" by Russia, which promised a response.

A year ago, Warsaw City Hall seized a former Russian diplomatic site, the subject of a legal dispute between Poland and Russia, to offer it to Ukraine fighting Russian forces. At the time, these were ten-storey buildings built in the 1970s in the south of the capital that had been used in the past by Soviet diplomats and then by the Russian embassy.
