Posters supporting Boston terror bomber Dzhokhar Tsarnaev have appeared on walls in Chechnya's capital of Grozny, according to the BBC.
It is not clear who is behind the posters declaring Dzhokhar Tsarnaev "not guilty", which appeared after Russia's May Day celebrations.
They show pictures of Mr Tsarnaev and his mother, Zubeidat, and include an appeal for online donations.
