At least 49 people are dead and 20 more are seriously injured following a pair of mass shootings at two mosques in Christchurch, New Zealand.

Two Locations

Both attacks began at lunchtime on Friday while the mosques in Christchurch's city center were crowded with worshipers.

Police reported that 41 people were killed at the al Noor mosque as another seven were killed at the Linwood mosque. Another victim died in hospital.

Police responded to the attacks after receiving the first reports at 1:40 p.m.

Witnesses described gunmen opening fire for "10 to 15 minutes," as one told reporters he prayed the shooter would "run out of bullets."

Police discovered a pair of explosive devices attached to a vehicle following the attacks and worked to disable them. A number of weapons were also recovered at both shooting locations.

Another "location of interest," over 200 miles away from Christchurch in Dunedin, was evacuated on Friday night.

Authorities were treating the incident as ongoing Friday evening, and warned Christchurch residents to stay indoors.

Attacker Live Streamed Shooting

One of the attackers appeared to post a lengthy manifesto to social media just before the attack, and police say that one of the shootings was live streamed on the internet.

"We would strongly urge that the (video) link not be shared," New Zealand police said. "We are working to have any footage removed."

Representatives for Facebook, Google, YouTube, and Twitter have publicly announced they will work to keep video of the attacks off their platforms.

Australian Suspect Charged With Murder

Four people were arrested Friday, but police say one was "not related to these events."

An Australian man in his late twenties has been charged with murder. He is set to appear in court Saturday morning. Two other men and one woman were arrested in relation to the attacks, but one of those detained was later released.

Police say it's still unclear what role the other two suspects in custody played in the attack.

New Zealand Police have declined to discuss "the offenders' possible motivations," but Australian Prime Minister Scott Morrison said the shooting was committed by an "violent, right-wing, extremist terrorist."

Reactions From World Leaders

In a press conference on Friday, New Zealand's Prime Minister Jacinda Ardern called the attack one of the country's "darkest days," and said the perpetrator's "extremist views" have no place in New Zealand.

She also said the shootings "can now only be described as a terrorist attack."

President Trump offered his condolences on Twitter, extending his "warmest sympathy and best wishes" to New Zealand.

"Forty-nine innocent people have so senselessly died, with so many more seriously injured," he wrote. "The U.S. stands by New Zealand for anything we can do. God bless all!"

British Prime Minister Theresa May also expressed her "deepest condolences" to New Zealand, calling the day's events a "horrifying terrorist attack" and a "sickening act of violence."

Britain's Queen Elizabeth II wrote that she was "deeply saddened by the appalling events in Christchurch today," before paying tribute to emergency services and volunteers supporting victims of the attack.

Pope Francis offered his "heartfelt solidarity" according to the Vatican's Secretary of State Pietro Parolin, and said he was "deeply saddened to learn of the injury and loss of life caused by the senseless act of violence."
