ROME (AP) — Three tourists, including a brother and sister from Britain, were among four people who were killed when a mountain cable car plunged into a ravine south of Naples, an Italian official said Friday.

An Arab woman with Israeli citizenship was the third foreign victim to be identified following Thursday’s accident, said Marco De Rosa, a spokesperson for the mayor of Vico Equense.

The fourth victim was the Italian driver of the cable car. A fifth tourist, said to be the brother of the Israeli victim, is in a stable but critical condition at a Naples hospital, officials said.

Initial reports suggested that a traction cable may have snapped as the cable car ascended Monte Faito, in the town of Castellammare di Stabia. The cable car plunged into a ravine after stopping very close to the station at the top of the peak, at around 3,400 feet.

Sixteen passengers were helped out of another cable car that was stuck mid-air near the foot of the mountain following the incident.
