At least 50 people have been confirmed killed as a result of Friday’s mass shootings at two mosques and another location in Christchurch, the largest city in New Zealand's South Island; dozens more remain in hospital and are being treated for gunshot wounds.

Axar.az reports that, Sky New Zealand has pulled its fellow independently-owned broadcaster Sky News Australia off air due to the distressing footage of the Christchurch mosque shooter’s Facebook live stream.

“We stand in support of our fellow New Zealanders and have made the decision to remove Sky News Australia from our platform until we are confident that the distressing footage from yesterday’s events will not be shared,” Sky New Zealand tweeted on Saturday.

New Zealand police, in turn, stated that they know that the “extremely distressing footage” of the Christchurch massacre continues to circulate online.

“We would strongly urge that the link not be shared. We are working to have any footage removed,” police pointed out.

Meanwhile, Facebook, Twitter and Google are facing scrutiny after reports that hours after the Christchurch attack, copies of the footage were still available on Facebook, Twitter, YouTube, as well as Facebook-owned Instagram and WhatsApp despite the social media giants’ claims that they had removed the videos.

Multiple weapons and a stash of ammunition were reportedly filmed by the man, who called himself Brenton Tarrant, in the 17-minute video which showed him arming himself, walking into a mosque and shooting indiscriminately in the Christchurch attack in New Zealand which left 50 people dead and 48 more injured.
