Staff at the Irish charity Concern Worldwide in the Congolese city of Goma have been evacuated amid warnings of an imminent volcanic eruption.

Tens of thousands of people are fleeing the eastern Democratic Republic of Congo city, fearing another volcanic eruption by Mount Nyiragongo, which spewed lava near the city last week.
