South Africa gripped by anti-migrant protests as foreign national is killed

Meanwhile, as global efforts to raise awareness of lead poisoning intensify, teams in Ivory Coast go door-to-door testing homes for dangerous levels of the toxic metal. Finally, Ivorian authorities are cracking down on illegal mining over fears of pollution, but some young people say the activity remains one of their few sources of income.
