"The motive of the person or persons involved in the Christchurch terrorist attacks is just a symptom of a greater disease in the west", said Walid.
The prime minister noted that it appeared the attacks appeared to have been well planned.
Trump's remarks were echoed by White House Press Secretary Sarah Sanders, with the administration spokeswoman describing the attack as "vicious act of hate" and saying the U.S. stood "in solidarity with the people of New Zealand and their government". "They may even be refugees here", Prime Minister Jacinda Ardern said Friday.
"We know that from this devastation and deep mourning, the people of New Zealand will unite to show that such evil can never defeat compassion and tolerance".
In his screed, the suspected gunman said he had been planning the attack for two years. He also claimed he contacted an anti-immigration group called the reborn Knights Templar and got the blessing of Anders Breivik for the attack.
"I am of the firm believe that we have a problem in this country".
The Christchurch terrorist's 74-page manifesto contains passages which eerily echo the same sentiment as Yair Netanyahu using language like the "Turk invaders now occupying our lands" and, "We are coming for Constantinople and we will destroy every mosque and minaret in the city". He said he had a regular childhood but had little interest in education. He said he earned money investing in Bitconnect, an open-source cryptocurrency. He predicted he would feel no remorse for their deaths. He also said there "was a racial component to the attack" and described it as "anti-immigration" and "an attack in the name of diversity".More news: Saudi rights official says pursuing justice for Khashoggi murder

What is awesome, however, is that Tarrant's entire manifesto is primarily based on an Islamophobic and anti-immigrant angle. "And those values, I can assure you, will not, and cannot, be shaken by this attack".
People in the 8chan forum praised the gunman's post.
New Zealand, which has had only a handful of mass shooting incidents in the past, has a Muslim population of over 1 per cent, according to a 2013 census.
There are unconfirmed reports that the shooter was influenced by Alexandre Bissonnette, the Laval University student convicted of killing six people at a mosque in Quebec City in January 2017.
The writing also cites military leaders and refers to ancient battles such as the 1189 Siege of Acre and Ottoman Empire battles including the 1863 battle of Vienna and the 1877 battle of Shipka Pass.
Tarrant livestreamed the shooting to social media, sharing the horrifying video to Facebook.
Peneha, who lives next door to the mosque, said the gunman ran out of the mosque, dropped what appeared to be a semi-automatic weapon in Peneha's driveway, and fled. "People, they're just sitting in front of their phones and computers and just mourning".
Schools and council buildings in Christchurch have been on lockdown, and the police have cautioned residents against leaving home. A second shooting at the Linwood Mosque, about 3 miles away, left seven people dead there.
Christchurch, a relatively small city on New Zealand's south island, hit global headlines in 2011 when it was struck by a deadly quake, killing more than 180 people.
