A-League: Kosta Barbarouses' touching goal celebration honours Christchurch victims

New Zealand international Kosta Barbarouses has paid his respects to the victims of the Christchurch terror attack with a touching goal celebration.

Playing for the Melbourne Victory in the A-League, the 29-year-old scored twice as he led his team to a 2-1 win against the Brisbane Roar on Saturday night.

After scoring the game's first goal in the 24th minute, Barbarouses dropped to his knees, bowing his head in what appeared to be an imitation of a Muslim prayer.

Barbarouses' actions didn't go unnoticed, as people took to Twitter to praise the striker.

In total, 49 people innocent people were killed in separate attacks at the Deans Ave and Linwood Ave mosques in Christchurch on Friday afternoon.

Three people are in custody, and one - Australian-born man Brenton Tarrant - has been charged with murder.

Police say other charges will follow, and an update on the other two suspects who are yet to appear in court is expected in at a press conference at 9:30am on Sunday.
