Leaders, organisations and the media around the world expressed disgust and sorrow at the killing of 49 people in shootings at two New Zealand mosques on Friday, attacks that many blamed on the demonisation of Muslims by the West.

Western leaders from Donald Trump to Theresa May expressed solidarity with New Zealanders, deploring what the White House called a "vicious act of hate".

The response from some Muslim countries went further, blaming politicians and the media for stoking that hatred. The nationalities of the victims included Indian, Pakistani, Malaysian, Indonesian, Egyptian, Bangladeshi, Saudi, Somalian and Turkish, authorities said.

New Zealand police said 50 people were killed and 42 were being treated for wounds, including a four-year-old child.

Brenton Tarrant appeared in court on Saturday charged with murder over the attack. Police said more charges would follow.

Here's a round up of the reaction around the world.

Prime Minister Jacinda Ardern described the tragedy as a "terrorist attack" and noted many of the victims could be migrants or refugees.

She pronounced it "one of New Zealand's darkest days."
