The humanitarian crisis caused by volcanic eruptions on the Caribbean island of St Vincent will last for months, a UN official has warned.
Didier Trebucq said nearby islands including Barbados, Antigua and Barbuda could also be badly affected.
About 20,000 people have been evacuated from their homes since La Soufrière volcano began erupting last Friday.
It had not previously erupted since 1979.
Mr Trebucq, the UN co-ordinator for Barbados and the Eastern Caribbean, said clouds of ash and smoke were continuing to pour from the volcano every day.
