Italian media said the British couple killed in a cable car crash near Naples were named Elaine Margaret Wynn and Graeme Derek Wynn.
The Mountain Cable Car Cabin jumped into the ground after one of the cables snapped Thursday, local officials said.
The cable car operator said he passed a safety inspection just two weeks ago and a criminal investigation was held.
The Ministry of Foreign Affairs said it was in contact with local governments but has not confirmed the identity of the victim.
The other two victims include a cable car driver named Carmaine Palat, 59, by authorities, and an Israeli woman identified as Janansuliman.
The fifth person in the cabin, Ms Sliman, brother, was “very seriously injured” after crashing and was airlifted to a hospital where she remains in critical condition, officials said.
Authorities at Torre Annunziata have launched an investigation into the cause of the crash.
Sixteen people were rescued from a second cabin, which is also in the queue near the bottom of the valley at the time of the incident. They were winched safely.
The mayor of Castellammare Di Stapia, a cable car, said the traction cable is believed to have been snapped.
“The downstream emergency brake worked, but it was clearly not on the shed that was about to reach the top of the hill,” he told Italian media on Thursday.
He added that there were regular safety checks on the cable car line, which runs three kilometres from the town to the top of the mountain.
Shortly after the crash, Italian Prime Minister Giorgia Meloni, who was traveling to Washington, expressed his “expressing sincere and pathetic dol” to the victims’ families.
Fight Mountain Cable Car has been operating since 1952. A similar accident on the Line in 1960 killed four people.
