JUST IN: Death toll in New Zealand mosque attacks rises to 50, police say.

Fifty people were killed and 50 others were wounded in the attack, New Zealand Police Commissioner Mike Bush told reporters.

The death toll had been previously reported as 49.

A Syrian refugee and his teenage sons, a Pakistani academic and a blossoming student are among the victims of Friday's attacks, the biggest massacre in New Zealand's modern history.

As authorities begin to release information on the victims, here's what we know so far.

New Zealand Police Commissioner Mike Bush is about to speak to reporters in Wellington to provide an update on the Christchurch attack.

Watch it here.

A group of people in Melbourne, Australia, took part in a vigil for the victims of the attacks at two Christchurch, New Zealand, mosques, according to Zahraa Albadri.

They put out 49 prayer mats with candles for the 49 victims.

Here's a photo from the scene:

Wasseim Alsati, who survived the Christchurch terror attack, posted a Facebook video from his hospital bed on Friday thanking people for their support.

In the caption, Alsati says he was shot three times and "was in a lot of pain."

Here's what he said:

Hi guys, how are you? I'm very sorry to miss your calls and text messages. I will not be able to answer anyone for now. I am really tired. Okay, guys? Please pray for my son, for me and for my daughter. Hopefully she will be so much better. Okay? I'm just posting this video to show you that I am fully okay. Okay, guys? It's been a pleasure to know you all, guys. Thank you for all the support and all the help that you have given me so far. God bless you all.

This photo was taken at 2:45 a.m. across the street from the Al Noor mosque, where 41 people were killed on Friday.

Flowers line the area behind the police tape and candles are burning to remember the victims.

In a video on Twitter, police officers were seen earlier taking flowers from a memorial into their police car so they could place them outside the mosque.

A hotel owner confirmed to CNN that Christchurch shooting suspect Brenton Tarrant visited Pakistan in October 2018.

"He was a regular tourist," owner Syed Israr Ahmed told CNN. "All I remember was that he was a fan of local food. He would leave the hotel in the morning and come back in the evenings." 

Ahmed owns Osho Thang Hotel in Pakistan's northern town of Nagar. He posted a picture of Tarrant online when he visited the hotel but has since removed it.

Six Pakistanis were among the 49 people killed in the mass shooting on Friday, Pakistan's Foreign Ministry confirmed.

The New Zealand Police Association says it fully supports Prime Minister Jacinda Ardern's calls to change the country's gun laws.

“Jacinda Ardern has said emphatically that New Zealand’s gun laws will change and that now is the time for that change,” Police Association President Chris Cahill said in a statement.

Cahill added that the debate that New Zealand is about to have on access to certain firearms should be short and swift.

“There is no place in the upcoming debate for the radical gun lobby which has made its presence felt in previous attempts to make our country safer," he said. "That input undoubtedly contributed to the rejection of most of the select committee recommendations on tightening our gun laws."

He continued:

New Zealand's weapons legislation is considered more relaxed than most Western countries outside of the US. Gun owners do need a license but they aren't required to register their guns -- unlike in neighboring Australia.

That said, gun-inflicted deaths are relatively low in New Zealand. 

United Kingdom Home Secretary Sajid Javid called the livestreaming of the New Zealand attack "absolutely repellant," and called on tech companies to do more to stop the video from spreading.

“Online platforms have a responsibility not to do the terrorists’ work for them,” Javid wrote in an article for The Daily Express on Saturday.

He added that the attacker filmed the shooting “with the intention of spreading his ideology.”

"Allowing terrorists to glorify in the bloodshed or spread more extremist views can only lead to more radicalisation and murders," Javid said.

Javid also called upon people to stop viewing and sharing the “sick material."

He mentioned a new policy proposal that will be introduced in the UK to ensure that tech companies that don't "clean up their platforms" would have to answer to the law.

Italy's Minister of the Interior Matteo Salvini was asked whether attacks like the one in New Zealand could happen in his home country because of his aggressive, anti-immigrant rhetoric.

"The only extremism that deserves attention is the Islamic one," Salvini said on Friday.

The far-right politician added that while any violence linked to extremists should be condemned, other forms of extremism like the right-wing extremism that inspired the New Zealand attacks were just "nostalgia."

“The fringes of the extreme right and the extreme left represent nostalgia, removed from world and from time, deserving of moral condemnation,” Salvini said. “If there is an extremism for which I set the goals of the acts I sign at the Ministry of the Interior, it is extremism of an Islamic mould."

Salvini has clashed with the European Union over his extreme stance on immigration.
