Russia said on Tuesday it had summoned Poland's chargé d'affaires to protest against what it called the "seizure" of its embassy school building in Warsaw last week.
Poland took over the building on Saturday, arguing that Russia was illegally occupying Polish state property. Russia called the move an "illegal seizure".
"These steps by Warsaw will certainly not go without a proper response from us, which will not take long," Moscow's Foreign Ministry said in a statement on Tuesday.
