Mozambique's government has banned protests following sustained post-election unrest that has left several people dead and dozens others injured. It follows last month's disputed presidential election, which Frelimo, the party that has governed Mozambique since 1975, won. The weeks-long protests have led to violent clashes with the police and at least 18 people have been killed, according to Human Rights Watch. Interior Minister Pascoal Ronda has urged Mozambicans to cooperate with the authorities to stop the protests, terming them "acts of terrorism". Demonstrations started at the end last month in the capital, Maputo, after Daniel Chapo, the Frelimo candidate, was officially declared the winner with more than 71% of the vote.
