Investigations to root out Islamophobia are spreading across the world.
In Austria, a far right-activist is being questioned over ties to the gunman. Martin Sellner was still livestreaming his day after Austrian intelligence services raided his home.
He told his audience he'd discovered a disproportionately large donation with an email address with the last name of the gunman.

Sellner denies any contact with the accused, but is now being investigated under anti-terror laws.
It's a sign of the increased vigilance from officials worldwide, and comes as Winston Peters lands in Kuala Lumpur for two days of meetings.
Prime Minister Jacinda Ardern says that trip now takes on additional significance.
"Those nations who have Muslim communities certainly are watching New Zealand presently, so certainly that adds an extra focus."
Peters is meeting with Malaysia's Deputy Prime Minister, who was among the first to express condolences for the family of Malaysian teen Muhammad Haziq.
The 17-year-old was killed in the attack, while his father and two other Malaysians were injured. Vigils were held for them in Penang this week.
The focus on New Zealand appears to have made Malaysians more interested in living here, with 165 registrations of interest from the country since the attack - part of a 33 percent increase overall in the numbers kept by Immigration New Zealand.
But the largest spike in inquiries about moving here in the last week have come from the US and Britain. There's also been a spike in Islamophobic crimes in those countries.
In Escondido, California, a mosque was set on fire. Local police say a reference to the Christchurch shooting could be seen in graffiti.
