Hundreds of buildings were damaged or looted, including schools and hospitals, in a wave of unrest after Daniel Chapo was confirmed as the winner of the presidential election.

Mozambique’s Oct. 9 presidential election was won by the ruling party candidate Daniel Chapo with 65% of the vote, the country’s top electoral court ruled, slightly reducing his initially-reported support while still leaving him the clear winner.

More than 1,500 prisoners escaped from a prison near Maputo on Wednesday, taking advantage of the third day of unrest triggered by the controversial confirmation of the long-ruling Frelimo party as the winner of recent elections.

A ruling on Monday confirming that Daniel Chapo had won a disputed election has sparked protests and violence.

At least 21 people have died since Monday due to political unrest in Mozambique as a political opposition leader vows to become president after losing in questionable elections.
