Tens of thousands of people have been evacuated from the city of Goma in the Democratic Republic of Congo over fears of another volcanic eruption.
Local authorities have said Mount Nyiragongo could erupt once again with little warning.
The volcano, 10km from Goma, spewed lava over the weekend, killing 32 people and leaving thousands homeless, the UN says.
Thousands fled but some residents had started returning.
The area has been upset by more than 200 aftershocks which have destroyed several buildings, while two cracks several hundred meters in length have appeared in the ground.
Goma is a lakeside city where around 670,000 people live, according to UN estimates. End.
