Mozambique: police and protesters clash in Maputo after disputed election

It's been a day of unrest in Maputo, Mozambique, in the wake of the killing of two members of the political opposition on Saturday. This Monday, police fired tear gas at protesters, who were demonstrating against the killings and what they say is electoral fraud. Meanwhile, it's been six weeks since the Ugandan Olympian Rebecca Cheptegei was killed by a former boyfriend in Kenya. The attack underscores a troubling trend of male violence against female athletes. Finally, a week without new cases of the Marburg virus in Rwanda. A tenative sign of optimism in fighting the Ebola-like disease.
