UPDATE 08:59: The gunman reportedly livestreamed from a helmet camera for 17 minutes as he entered a Christchurch mosque and shot worshippers.
UPDATE 08:37: Police no longer warning that attackers may be at large.
UPDATE 08:14: 49 people have been confirmed dead as one man has been charged with murder, police confirm.
At least forty people have been killed and another 48 seriously wounded following two shootings at mosques in Christchurch, New Zealand.
Shootings have taken place at the Masjid Al Noor mosque in central Christchurch and at the Linwood Islamic Centre.
Three men and one woman are in custody, police commissioner Mike Bush said, but warned more suspects may be at large.
Police said a man who claimed responsibility for the attacks left a 74-page anti-immigrant manifesto in which he explained who he was and his reasoning for his actions.
The shooting has been described as one of the country’s “darkest days” and a “terrorist attack” by New Zealand prime minister Jacinda Ardern and an “extremist, right-wing violent terrorist [attack]” by Australian prime minister Scott Morrison.
Scott Morrison said one of those arrested was an Australian citizen.
Ardern said: “Many directly affected by this shooting may be migrants to New Zealand, they may even be refugees here…They are us. The person who has perpetuated this violence against us is not.”
The person who has committed this violent act has no place here. To those in Christchurch; I encourage you to stay inside and follow the instructions of @nzpolice. The Police Commissioner will be making a public statement at 5pm. I will update everyone again later this evening.

An attacker is believed to have live streamed at least one of the shootings and police have urged people not to share the footage online.
Police are aware there is extremely distressing footage relating to the incident in Christchurch circulating online. We would strongly urge that the link not be shared. We are working to have any footage removed.

Police have also found improvised explosives in cars and have carried out a controlled explosion at New Zealand’s largest train station, the Britomart Transport Centre.
An international cricket match between New Zealand and Bangladesh has been cancelled after the terror attacks.
