Austrian leader Sebastian Kurz has confirmed a financial link between the accused Christchurch mosque gunman and a far-right group.
Fifty people were killed when a gunman opened fire inside the Deans Ave and Linwood Ave mosques on Friday, March 15.

Prosecutors said Identitarian Movement leader Martin Sellner received €1500 (NZ$2483) in early 2018 from a donor with the same name as the man charged with murder following the Christchurch attack.
"We can now confirm that there was financial support and so a link between the New Zealand attacker and the Identitarian Movement in Austria," Kurz said.
Electronic devices were seized from the home of Martin Sellner on Tuesday after Austrian intelligence found he had received a "disproportionately high donation" from a person with the same surname as the accused Christchurch gunman.
Kurz tweeted his support of the investigation when the search took place.
"Every connection between the Christchurch suspect and members of Identitarians in Austria must be cleared completely and ruthlessly," Sebastian Kurz tweeted.
Sellner published a YouTube video after the search in which he said he had received a donation from the man and that police had raided his house over possible links to the Christchurch attacker.
In it, he said: "I'm not a member of a terrorist organisation. I have nothing to do with this man, other than that I passively received a donation from him."
The man accused of committing the Christchurch terror attacks travelled to Austria among other European states last year.
Bacher said an investigation was underway about whether there were criminally relevant links between Sellner and the attacker.
The Austrian Interior Ministry declined to comment.
Kurz said Austria was looking into dissolving the Identitarian Movement, which says it wants to preserve Europe's identity.
"Our position on this is very clear, no kind of extremism whatsoever - whether it's radical Islamists or right-wing extremist fanatics - has any place in our society," Kurz said.
Austrian Vice-Chancellor Heinz-Christian Strache, of the far-right Freedom Party (FPO), said the FPO had nothing to do with the Identitarian Movement.
