Mozambique’s main opposition leader said he’ll announce plans for renewed protests against the outcome of October elections later this week, a phase he has suggested will be more severe than previous demonstrations in which scores of people have died.

The death toll from the protests has reached 278, with most fatalities caused by police bullets, according to Decide Platform, a local monitoring group.

The death toll inflicted by Mozambique’s post-election unrest has climbed to 261, according to a local monitoring group, with most of the fatalities caused by police gunfire.

Post-election violence has spread across Mozambique, paralyzing cities and disrupting daily life. As the chaos escalates, the United Nations calls for calm and a peaceful resolution.
