Angola: Mystery toxin in Angola schools

A wave of mysterious poisonings has hit hundreds over the last two days in Angolan schools, but police have yet to identify the toxin that has sown panic in the country, officials said on Friday. About 300 students from both public and private schools have been hit by symptoms that include vomiting, headaches, sore throats and sometimes suffocation, said Renato Paulata, director of a public hospital in Luanda.
