Police in Angola say four people have been killed and 500 have been arrested after demonstrations in the capital, Luanda.
What began as a three-day strike by taxi drivers against rising petrol prices has escalated into one of the most widespread and disruptive waves of protest the country has seen in recent years.
Thousands of people joined demonstrations in the capital on Monday that saw roads blocked, shops looted and clashes between demonstrators and police.
Pockets of protests continued in Luanda on Tuesday, along with further clashes with police and more looting of shops.
"The fuel price issue is just the last straw that has reignited widespread public discontent... People are fed up. Hunger is rife, and the poor are becoming miserable," a prominent local activist, Laura Macedo, told the BBC.
