The Associated Press reports that 49 people are dead, according to authorities in New Zealand, after a “carefully planned racist attack” at two mosques in Christchurch, a city on the East coast of New Zealand’s South Island. Authorities have three unidentified men and one woman in custody. One suspect has already been charged with murder. The attack was carried out as worshipers, many believed to be migrants and refugees, attended Friday prayer. Prime Minister Jacinda Ardern called the events “an extraordinary and unprecedented act of violence."
