Assistant Commissioner Neil Basu, head of Counter Terrorism Policing, said on Friday: "Whilst there is no intelligence linking these appalling events in Christchurch to the United Kingdom, additional uniform patrols will continue in London and nationally over the coming days, focusing on places of worship and specific communities".

Within hours of the massacre that killed 50 people, New Zealand Prime Minister, Jacinda Ardern, promised to change the country's gun laws, though she didn't immediately specify how.

Christchurch residents including the Muslim community are mourning the victims of the attacks.

Two other people were in custody and police said they were working to understand their involvement.

Abdul Aziz, 48, told local media he heard shooting and ran outside the mosque, shouting at the gunman and drawing him away from the building, the Newshub website reported.

Throughout the hearing, Tarrant, who had a cut on his upper lip, remained silent and looked at the media persons in the public gallery. He will be in custody until April 5, according to the High Court in Christchurch.

New Zealand has raised its security threat level to the highest.

Muslims account for just over 1 percent of New Zealand's population.

New Zealand Police Commissioner Mike Bush said additional charges are forthcoming. "There is a dimming of enlightenment in many parts of the world". The nationalities of the victims included Indian, Pakistani, Malaysian, Indonesian, Egyptian, Bangladeshi, Saudi, Somalian and Turkish, authorities said.

Bangladesh says three of its citizens are among the dead, another five injured - two seriously. A four-year-old girl has been transferred to the Starship Hospital in Auckland.

The KKW Beauty mogul, who has advocated for prison reform in the U.S.in the past, took to Twitter Saturday morning to compliment New Zealand officials after news broke the country will ban semi-automatic weapons after the deadly attack.

The shooter, who had a gun license acquired in November 2017, carried out the killings with two semi-automatic weapons, two shotguns and a lever-action firearm, Ardern said.

Watch: PM Ardern's comments on tightening gun laws. "As is the entire nation, we are all unified in grieving together", she told reporters.

Australian Prime Minister Scott Morrison on Friday called the massacre the work of an "extremist right-wing, violent terrorist".

Brenton Tarrant, a self-described fascist, has been charged with murder in the shooting.

Mohamed Hassan, a journalist who lived in New Zealand for most of his life, says Muslims have been grieving alongside numerous other communities.

Ardern said the suspect traveled around the world and was in New Zealand sporadically.

None of those arrested had a criminal history or were on watchlists in New Zealand or Australia.

The Church of Jesus Christ of Latter-day Saints' Pacific Area Presidency also released a statement of support for Muslim communities and all others impacted by the Christchurch shootings. "I am very sorry to miss your calls and text messages.I am really tired.please pray for my son, me and my daughter.I am just posting this video to show you that I am fully ok", said Wasseim Alsati, who was reportedly shot three times.
