As Riga Russian Theatre's actors rehearse the season's big premiere, "Lady Macbeth", they know the play's poster will not crop up around the Latvian capital as it normally would. The city council has prohibited the theatre from advertising its shows in Russian -- the language of the Baltic state's biggest minority. The use of the language and more generally the rights of ethnic Russians living in Latvia have become sensitive issues in a country that fervently backs Ukraine in its fight against Russia's invasion. "There are bad people, there are good people and there is language and culture, which in principle belong to no one," says theatre director Dana Bjork. IMAGES AND SOUNDBITES
