Police in Mozambique have reportedly said that two albino children have been kidnapped in two separate incidents in the southern African country. According to BBC, the kidnapping of the children aged 4 and 11 took place at night while they were sleeping. Police said investigations were under way. An aunt of one of the boys said the kidnappers took her nephew while he sleeping with his grandmother and their calls for help were not answered. "The child was sleeping with his grandmother when the bandits came at night and took him away. We shouted for help, but no neighbour came to our rescue. The criminals were travelling on a motorbike," she was quoted as saying. A report by AFP said that albinos in Mozambique were often hunted for their body parts, which were used as charms and magical potions in the belief that they brought wealth and good luck.More than 100 attacks against albinos in Mozambique have been reported since 2014, according to the United Nations.* Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
