NAPLES, Italy — Two Italians died early Sunday in a car accident involving a U.S. sailor from Naples.

The petty officer third class was traveling alone when the accident occurred at about 5:15 a.m. in a tunnel on the Tangenziale, the main highway through Naples, said Lt Cmdr. Jacky Fisher, spokeswoman for Naval Support Activity Naples.

The sailor, assigned to the security department, is in stable condition in an Italian hospital, Fisher said. His name is not being released pending next-of-kin notification.

Though details are sketchy, Italian news said the two Italian men, ages 21 and 19 from the Naples suburb of Casoria, had gotten out of their vehicle in the Camaldoli tunnel. News reports differed on whether there was a problem with their vehicle or whether they had been involved in an earlier accident.

The sailor’s 2004 Volkswagen Jetta apparently hit the two men. One died at the scene, and another died at a local hospital.

Naples authorities are investigating the incident with the cooperation of U.S. authorities.

It is the second fatal accident this summer involving a sailor from Naples.

On June 12, three Naples sailors were killed and two seriously injured in a fiery accident when their car flipped.
