At least 21 people have been killed in Mozambique and scores injured in protests in which demonstrators have burned tyres, blocked roads and marched to Frelimo offices.

South Africa has closed one of its busiest border crossings with Mozambique following violent post-electoral protests in the neighbouring country. The protests have led to deadly clashes in several cities following last month's disputed presidential election, won by Mozambique’s ruling Frelimo party.

This came as South Africa's Border Management Authority temporarily closed its border post with the neighboring Mozambique due to security concerns following the ongoing post-election unrest.
