Tourists were forced to swim for six hours and drink their own urine after a boat sank in Indonesia.

Two Britons are in hospital and 15 other people are missing.

The group was travelling between Lombok and the Komodo Islands in eastern Indonesia near Bali when the boat sank at about 7pm local time last night.

Ten people were rescued, reportedly from New Zealand, Spain, France, Germany and the Netherlands, as well as the two Britons.


They had to swim for hours to reach a remote island where a volcano was erupting.

The group reportedly spent the night there and drank their own urine.

A spokeswoman for the Foreign Office said: ‘We are aware that two British nationals have been hospitalised following an incident in West Nusa Tenggara, Eastern Indonesia, on August 17. We are providing consular assistance.

‘We are in contact with the local authorities about the incident and stand ready to offer consular assistance to any other British nationals who may be involved.’
