At least 49 people have been killed in a terror attack in New Zealand.

Gunmen opened fire at two mosques in Christchurch as Friday prayers were taking place.

One man has so far been arrested and charged with murder. He had posted a 74-page manifesto online prior to carrying out the attack, in which he outlined his anti-immigrant motives.

The attack was also live-streamed on Facebook.
