They say the lives of the children, ages 8 and 14, are threatened by the exposure to carbon monoxide that apparently came from a boat generator. Italian media identified the dead man as a 57-year-old businessman from Sicily, Eugenio Vinci.
Five other boat passengers were hospitalized but are not in serious condition. Croatian media initially reported the group fell sick after eating shellfish in a restaurant on the island of Hvar. Police closed the restaurant briefly but a health inspection found no problems.
