Calderdale in shock after people killed in New Zealand mosque shootings

Police also defused explosive devices in a auto.

The suspect has been charged with murder while three other people have been held in custody. Police said they were trying to determine how they might be involved.

Prime Minister Jacinda Ardern said some of the victims may have been new immigrants and refugees.

In addition to the dead, health officials said 48 people were being treated at Christchurch Hospital for gunshot wounds. Injuries range from critical to minor.

Three other people - two men and a woman - were also arrested. At least one, though, is not believed to have had anything to do with the shooting. Dunedin is a city near the southern tip of New Zealand, around 225 miles from Christchurch.

Police said the investigation had extended 360 kilometers (240 miles) to the south, where homes in Dunedin were evacuated around a "location of interest". They gave no details.

At the White House, Trump called the bloodshed "a bad thing" but rejected any suggestion the white nationalist movement is a rising threat around the world, saying it is "a small group of people that have very, very serious problems".

A man who claimed responsibility for the shootings, 28-year-old Brenton Tarrant, an Australian citizen, left a 74-page manifesto in which he explained who he was and his reasoning for the attack, although police have not confirmed he is the shooter.

Police patrols are being stepped up around mosques in Peterborough following the terrorist attack in New Zealand.

British Prime Minister Theresa May offered deepest condolences "after the horrifying terrorist attack in Christchurch".

"Many of those affected may be migrants to New Zealand".

Referring to the four people detained by police, Ardern said, "These are people who I would describe as having extremist views that have absolutely no place in New Zealand".

Bush said police had found two improvised explosive devices in one auto, a clarification from an earlier statement that there were devices in multiple vehicles.

"We have one person in custody but we are unsure if there are other people".

The deadliest attack occurred at the Al Noor mosque in central Christchurch at about 1:45 p.m., when 41 people were killed.

He opened fire with a semi-automatic shotgun and a rifle on a reported 100 defenceless worshippers attending Friday prayers. He said he then went into the mosque to try to help.

"The content of the video is disturbing and will be harmful for people to see", he said.

"I stand in sympathy and solidarity with the Muslim community in Peterborough".

A fourth person was apprehended but later released after it was determined to be an armed bystander trying to help authorities.

One man, with blood still on his shirt, said in a television interview that he hid from the gunman under a bench and prayed that he would run out of bullets.

A gunman broadcast live footage on Facebook of the attack on one of the mosques, showing him driving to the scene, entering the building and shooting people at random.

He adds: "I am just a regular White man, from a regular family".

The online video footage, which appeared to have been captured on a camera strapped to the gunman's head, showed red petrol canisters in the back of his vehicle, along with weapons.

In the video, the shooter parks his auto next to the mosque and gets out of the vehicle with a rifle. He walks back into the mosque, where there are at least two dozen people lying on the ground.
