Online video sharing service YouTube has apologised for a translation error that misrepresented Polish Prime Minister Mateusz Morawiecki by suggesting that Nazi German death camps "were Polish", the media reported. Polish Press Agency reported on Saturday that YouTube apologised for the error caused by "automatic translation", according to Xinhua. Morawiecki made a public TV address on Thursday about a controversial anti-defamation bill, outlawing historically inaccurate use of the term "Polish death camps" among other provisions.
