International Desk: Forty-nine people have been killed and at least 20 wounded in shootings at two mosques in Christchurch, New Zealand.
Australian Prime Minister Scott Morrison described the gunman, who had Australian citizenship, as an "extremist, right-wing" terrorist.
Four people - three men and one woman - were detained in connection with the shooting, New Zealand police said.
New Zealand Prime Minister Jacinda Ardern called it one of New Zealand's "darkest days".
New Zealand police commissioner Mike Bush confirmed that "multiple fatalities" were recorded at two locations.
The first report of an attack came from the Al Noor mosque, located in central Christchurch. Witnesses told local media they ran for their lives, and saw people bleeding on the ground outside the building.
A second mosque in the suburb of Linwood was evacuated, but there were fewer details from that site. Police also defused "a number of IEDs (explosive devices) attached to vehicles", Mr Bush said.
Authorities advised all mosques in the city to shut down until further notice. Armed police were also seen at Papanui High School in Christchurch, which was cordoned off.
It was not immediately clear how many gunmen there were. The Australian suspect is believed to have published a manifesto outlining his intentions, in which he espoused far right and anti-immigrant ideology.
He also appeared to have livestreamed on Facebook from a head-mounted camera as he shot victims in a mosque. Police called on the public not to share the "extremely distressing" footage online.
Facebook said it had removed the shooter's Facebook and Instagram accounts and was working to remove any copies of the footage.
One unnamed survivor told TV New Zealand he was at the Al Noor mosque, and saw a gunman shoot a man directly in the chest. The attacker reportedly targeted the men's prayer room in the mosque, then moved to the women's room.
"What I did was basically just waiting and praying, God please, let this guy run out of bullets," the witness said. "He came to this side, he shot this side, he went to another room and went to the ladies' section and shot them. I just heard one of the ladies has died."
A Palestinian man who asked not to be named told the AFP news agency he heard rapid gunfire and saw a man shot in the head.
"I heard three quick shots, then after about 10 seconds it started again - it must have been an automatic, no one could pull a trigger that quick," he said. "Then people started running out. Some were covered in blood."
