The prime minister of New Zealand, Jacinda Ardern, said she would seek a change in her country's gun laws after at least one man opened fire during afternoon prayers Friday and killed at least 49 people at two mosques in Christchurch.
"Our gun laws will change," Ardern declared in a news conference Saturday morning local time.
The violent attack struck at the very heart of New Zealand, a country that prides itself on being both peaceful and diverse.
More than 40 people were treated for injuries sustained in the attacks in Christchurch, police said.
The chief of surgery at the Christchurch hospital, Greg Robertson, said that of the 48 people originally admitted, 39 are still hospitalized in the Christchurch hospital, 11 in intensive care and critically ill. A 4-year-old girl was transferred to another hospital. Four people died on the way to the hospital, he said.
Robertson said it is unusual for local surgeons to treat gunshot wounds. But he noted that they've seen things that have been "pretty terrible" in the earthquake of recent years. He said they've had this experience "and we wouldn't want to get more."
New Zealand police have charged a 28-year-old man with murder and he has made an initial court appearance that lasted about a minute, according to the Associated Press.
Two other people were taken into custody and police continue to investigate their possible connections to the shootings. A fourth individual who had been arrested turned out to have been an armed man who was trying to assist the police, Ardern said.
The prime minister also revealed that the suspected "primary perpetrator" and his apparent accomplices were not on any terror watchlist in New Zealand or Australia. Ardern added that the suspect had a gun license and legally purchased his weapons.
"We are seeking answers," she said in relation to how the gunman, a citizen of Australia, entered New Zealand.
Ardern said he had two semi-automatic weapons and two shotguns. She says a lever-action shotgun "was also found."
New Zealand Police Commissioner Mike Bush, in a new conference, praised the quick work of local authorities in responding to the first reports of gunfire at the mosque. A police official said the suspected gunman was taken into custody 36 minutes after police were summoned to the mosque.
Bush also said that New Zealand authorities are working closely with Australian police and intelligence agencies to learn more about the gunman.
"This person was not known to any of us, hadn't been reported to any of us, has no previous convictions that we can understand, was not a person of interest to either jurisdiction," Bush added.
Police said an explosive device was found in a car belonging to the gunman.
"You don't think that something like this could happen in New Zealand," a young woman named Yasmin Ali told reporters. "In Christchurch of all places. We're such a small community. We're so kind and loving, so I just don't understand why someone would hurt us like this."
Most of those killed were worshiping at Al Noor Mosque when the gunman entered. A second shooting targeted the Linwood Mosque, about 3 miles away.
Farid Ahmed told The Guardian he was at Al Noor during the attack and heard the shooter change magazines seven times. "When the shooting started people started rushing out, running out and the door is closed," recalled Ahmed, whose shirt was stained with blood. "There was a bench and I lied down and [hid] my half body under the bench and my legs are out, pretending to stop my breath."
Len Peneha said he lives next door to Al Noor and saw a black-clad man wearing a helmet enter the mosque. The sound of dozens of shots rang out, he told The Associated Press. Peneha said the man ran out, dropping a gun as he fled.
Peneha went inside to try help the victims. "I saw dead people everywhere. There were three in the hallway, at the door leading into the mosque, and people inside the mosque," he told the news service. "I don't understand how anyone could do this to these people, to anyone. It's ridiculous."
A man named Hassan told the Guardian he was worshiping at Linwood mosque when the shooting there started.
He said women around him rose up and screamed, "Do not come here," at the gunman that and some of them charged at the assailant.
"The shooter was screaming a lot and waving the gun in every direction, shooting, shooting, shooting," Hassan said. "I don't know who of my friends is dead or alive now. I am waiting. Police told me: 'I am sorry, this is the first time this has ever happened in this country.' "
Before the shootings, a man who identified himself as a white man from Australia allegedly posted a 74-page, hate-filled screed online, and then live-streamed the killings on Facebook. He has not been publicly identified by officials.
The massacre rocked a small, peaceful nation where such events are extremely rare. Following the attack, New Zealand's national security level was changed from "low" to "high."
Earlier, Ardern had described Friday as "one of New Zealand's darkest days." She called the shootings a terrorist attack, one that appeared to have been well planned. With a grim expression, she said the country seems to have been targeted because of its welcoming and tolerance.
"We were not chosen for this act of violence because we condone racism, because we are an enclave for extremism," Ardern said during a news conference in Wellington. "We were chosen for the very fact that we are none of these things. Because we represent diversity, kindness, compassion, a home for those who share our values, refuge for those who need it. And those values, I can assure you, will not, and cannot, be shaken by this attack."
Prior to Friday's attack, the country's deadliest shooting occurred in 1990, when a man killed 13 people following a dispute with a neighbor.
Christchurch is New Zealand's second-largest city, with a population of about 375,000 people. "Our city has changed forever today," Mayor Lianne Dalziel said in a statement. "It is beyond belief that something like this should happen in our city and in New Zealand."
In his screed, the suspected gunman said he had been planning the attack for two years. He claimed to represent Europeans and whites in a battle against immigrants, people he repeatedly described as "invaders." He also referred to the right to bear arms as laid out in the Second Amendment of the U.S. Constitution, and claimed that attempts to take away guns in the U.S. will lead to a civil war.
A front page of New Zealand newspaper The Dominion Post reflected the sense of shock and grief: "End of innocence."
New Zealand's ambassador-designate to the U.S., Rosemary Banks, told NPR that authorities are "convinced this particular event is over."
"We are a very diverse society, we have over 200 ethnicities, 160 languages...we have been very welcoming to outsiders," Banks said Friday. "For these people who are victims in these mosques — they are refugees, they are people who are from our migrant communities who've chosen to live in New Zealand, thinking they would find a safe place where they could be free in their religion and their culture."
The White House released a statement condemning the attacks. "Our thoughts and prayers are with the victims and their families. We stand in solidarity with the people of New Zealand and their government against this vicious act of hate."
The alleged gunman reportedly streamed 17 minutes of the attack on Facebook. The social media platform removed the video and removed the suspect's accounts. The company says it is working directly with the New Zealand Police, the country's national police force, in its investigation. In a statement, according to the AP, Facebook New Zealand spokeswoman Mia Garlick said that the company is "also removing any praise or support for the crime and the shooter or shooters as soon as we're aware."
Twitter and Google, which owns YouTube, say they're working to remove any video of the shootings from their sites, as well. Versions of the video reportedly persisted on the sites for hours after the shootings.
"You may have chosen us," Ardern said Friday, "but we utterly reject and condemn you."
