An Irish citizen and two Britons were among 16 tourists injured when their bus overturned on a road in Cuba.
Local reports said the government-operated vehicle left the road and overturned on Thursday evening local time, between Trinidad and Varadero, two major tourist destinations.
Nineteen people were said to be on board the bus at the time. The others injured were said to be two Czechs, four Dutch, one Filipino and six Russians.
State-run newspaper Cinco de Septiembre said three of the tourists were considered to be in a serious condition. Two underwent surgery and are in intensive care.
In a statement, the UK Foreign and Commonwealth Office said: "We are aware of a bus crash involving British nationals between Trinidad and Varadero in Cuba on the evening of July 4.
"Our embassy in Havana is in close contact with local authorities.
"Consular officials are on their way to the area to provide assistance if needed."
