A Tunisian man suspected of murdering an elderly couple in their Austrian home was a "radicalised Muslim" believed to have acted with an Islamist motive, Interior Minister Wolfgang Sobotka said Wednesday.
The killings in the northern city of Linz on Friday "clearly had an Islamist background", Sobotka told a press conference in Vienna, adding that the 54-year-old suspect, who handed himself in to police, "is clearly a radicalised Muslim".
