Seven people are missing after a sailing yacht sank off the coast of Sicily in the early hours of Monday morning, the Italian fire and rescue service has said.
The 56m (183ft) yacht was flying a British flag and four Britons are among those missing, Italian media has reported.
The 22 people onboard included 10 crew and 12 passengers - and also included American and Canadian nationals.
Emergency services rescued 15 people including a one-year-old child after the vessel encountered poor weather off the coast of Palermo.
A wreck has been identified at a depth of 50m, the fire brigade said, with divers searching for the missing people.
Eight of those rescued are receiving treatment in hospital, the Italian Coastguard said.
A statement from the Italian Coastguard said that a nearby boat offered assistance to people before emergency services arrived.
Local media have reported that the sailing yacht is called the "Bayesian".
The Bayesian’s publicly-available onboard tracker last transmitted near Porticello, just after 04:00 local time – shortly before rescue efforts reportedly began.
The ship is managed by Camper and Nicholsons International. A spokesperson told BBC Verify that they are currently “dealing with a situation onboard one of [their] managed vessels”, but would not confirm which vessel, or any further details.
The British foreign ministry had no immediate response to a request for comment.
