Two Britons are in hospital and 15 other people are missing after a tourist boat sank while travelling between islands in Indonesia.
Ten people, including the two British nationals, were rescued but it is unclear whether there were any more Britons on the boat.
A spokeswoman for the Foreign Office would not comment on their injuries but said: "We are aware that two British nationals have been hospitalised following an incident in West Nusa Tenggara, Eastern Indonesia, on 17 August. 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."
