A manslaughter investigation has been opened into the deaths of seven people in the sinking of a luxury yacht off the coast of Sicily, an Italian prosecutor said.

British tech mogul Mike Lynch and his 18-year-old daughter Hannah were among six people recovered after the Bayesian superyacht sank near Porticello at about 5am local time on Monday.
