Donald Trump condemns ‘horrible’ mosque attacks

WASHINGTON: US President Donald Trump condemned as a "horrible massacre" twin mosque attacks in New Zealand that killed at least 49 worshippers and wounded dozens more during Friday prayers.

The chief suspect, a 28-year-old Australian-born man, allegedly published a racist "manifesto" on social media before the attack, featuring conspiracy theories about Europeans being displaced, and details of two years of preparation and radicalisation leading up to the shootings.

"My warmest sympathy and best wishes goes out to the people of New Zealand after the horrible massacre in the Mosques. 49 innocent people have so senselessly died, with so many more seriously injured," Trump wrote on Twitter after the attacks in Christchurch.

Trump, whose rhetoric is sometimes aligned with the far right in the United States, added: "The US stands by New Zealand for anything we can do. God bless all!" Moments before, his spokeswoman Sarah Sanders said: "We stand in solidarity with the people of New Zealand and their government against this vicious act of hate."

"The United States strongly condemns the attack in Christchurch. Our thoughts and prayers are with the victims and their families," she added. In addition to the main suspect, two other men are in custody, although their link to the attack is unknown.
