People around the world expressed revulsion at the deadly shootings at two mosques in New Zealand on Friday as some countries revealed that their citizens had been caught up in the bloodshed.
The timing of the shootings in the city of Christchurch, during Friday prayers, and the social media posts of what appeared to be live, point-of-view video footage of the assault by a gunman added to the distress.
At least 50 people have been killed and more than 40 seriously wounded in the mass shootings.
"It is clear that this can now only be described as a terrorist attack," New Zealand's Prime Minister Jacinda Ardern said, adding it marked "one of New Zealand's darkest days."
The gunman who killed numerous worshippers in a New Zealand mosque on Friday was a right-wing terrorist with Australian citizenship, Prime Minister Scott Morrison said.
"We stand here and condemn, absolutely, the attack that occurred today by an extremist, right-wing, violent terrorist," Morrison told a press conference.
He confirmed media reports that the gunman who mowed down worshippers in the main mosque in the southern New Zealand city of Christchurch was an Australian-born citizen.
He said Australian security authorities were investigating any links between the country and the attack, but declined to provide further details about the gunman.
Morrison offered his sympathies to the people of New Zealand, one of Australia's closest neighbours.
"We are not just allies, we are not just partners, we are family," he said.
Hundreds of mourners attend Sydney mosque
Mourners packed the Lakemba Mosque in Australia's biggest city Sydney to pray for the victims of the Christchurch attack.
New South Wales parliamentarian representing Lakemba Jihad Dib said, "When hatred rears its head, we must stand together to ensure that humanity always wins out."
Bangladeshi Prime Minister Sheikh Hasina has sent a message to Ardern, expressing her "deep shock" and condemnation of the attacks on two mosques in Christchurch.

An international cricket match between New Zealand and Bangladesh has been cancelled after players from the visiting team narrowly avoided the mass shooting at one of the mosques.
Bangladesh's cricket board president says the team is safe in a locked hotel in Christchurch.
Prime Minister Justin Trudeau said Canadians are appalled by the attack and said they remember all too well the sorrow after a Canadian man shot dead six Muslim men in a Quebec mosque in 2017.
"Far too often, Muslims suffer unimaginable loss and pain in the places where they should feel safest," Trudeau said in a statement. "To move forward as a world, we need to recognise diversity as a source of strength, and not a threat."
Police stepped up security patrols at mosques across the country.
Danish Foreign Minister Anders Samuelsen said, "Extremism has again shown its ugly face." Denmark's Jewish community, which was targeted in a February 2015 attack where a guard was shot and killed, expressed "shock" at the news of the New Zealand attack.
French President Emmanuel Macron, also in a tweet, denounced the "odious crimes against the mosques in New Zealand" and said that France will work with international partners to fight terrorism.
The rector of the Grand Mosque of Paris condemned the attack in Christchurch, which left at least 50 dead.
France is increasing security measures at mosques and other religious sites after the deadly attack against two mosques in New Zealand.
French Interior Minister Christophe Castaner tweeted that he ordered regional prefects to send patrols and reinforce surveillance of places of worship "as a precaution."
France is home to western Europe's largest Muslim community. While French Muslim and Jewish sites are sporadically targeted by vandals, France has not seen a major attack on mosques of the kind that targeted New Zealand.
Germany's foreign minister says the attacks were a "brutal crime" that touches people of all religions around the world.
In two tweets, Foreign Minister Heiko Maas said Germany's sympathies were with the friends and families of the victims of the attack.
"The horrific terrorist attack in Christchurch targeted peacefully praying Muslims – if people are murdered solely because of their religion, that is an attack on all of us."
Maas added, "We stand at the side of the victims. Stay strong New Zealand!"
Britain's Queen Elizabeth, the head of state of New Zealand, said she was deeply saddened by the shootings.
"I have been deeply saddened by the appalling events in Christchurch today. Prince Philip and I send our condolences to the families and friends of those who have lost their lives," the queen said in a statement.
"I also pay tribute to the emergency services and volunteers who are providing support to those who have been injured. At this tragic time, my thoughts and prayers are with all New Zealanders."

London Mayor Sadiq Khan has also expressed solidarity with the people of New Zealand following the attacks on worshippers.
Khan said the news was "heartbreaking."
He says, "London stands with the people of Christchurch in the face of this horrific terror attack. London will always celebrate the diversity that some seek to destroy."
Khan sought to reassure Muslim communities in London following the attacks, saying that the Metropolitan Police would be visible outside mosques.
London mosques have been targeted in the past. One man died and several others were injured in 2017 when Darren Osborne drove a van into people leaving evening prayers.
Prosecutors say Osborne was motivated by a hatred of Muslims and had been radicalised by far-right propaganda he found online.
Gulf Arab states
Gulf Arab states are condemning the attack on the mosques in New Zealand.

Indonesia's ambassador to New Zealand, Tantowi Yahya, said enquiries were being made as to whether Indonesians were caught up in the attack. There are 331 Indonesians in Christchurch, including 134 students, the foreign ministry said.
Indonesia is the world's biggest Muslim country.
Iran's foreign minister says bigotry in Western countries has led to the attacks on Muslims in New Zealand.
