A man has been filmed launching an alleged racist attack on a Brisbane train security guard.
17-year-old Kader Boumzar was filmed racially abusing the guard after he had been asked to take his feet off the seat.
"Do you want to come to Australia and learn some proper English?" the man says. "Learn some fucking English, because this is Australia cunt and I can't understand you."
After several minutes of sustained abuse, an American-accented passenger intervenes: "What's your fucking story?" he says. "Get off the fucking train."
Boumzar attempted to excuse his actions on Facebook by claiming he was drunk, saying people were overreacting.
He later apologised for being a "fucking idiot" and claimed that his earlier Facebook post had been made by someone else.
Posted on Saturday afternoon on rapper Brisbane Fortafy's Facebook page, the video has been viewed 4m times.
Speaking in Brisbane, Prime Minister Tony Abbott condemned the attack and called it "un-Australian."
Queensland Rail congratulated the guard on his restrained response, and offered him their support.
Queensland State Premier Campbell Newman also condemned the attack.
