Three people have been killed and at least four others hurt in a car-to-car shooting and crash early on the Las Vegas Strip of the US state of Nevada, police say.

Initial reports had it as a gun battle between the luxury 4WD vehicle and the high-end sports car. But investigators do not think anyone in the Maserati was shooting, Sergeant John Sheahan said.

The early-morning crash occurred at a busy traffic junction surrounded by some of the most famous casinos on the Strip, including the Bellagio, Caesars Palace and Bally's.

The Range Rover fled the scene.The driver of the Maserati lost control of the car and crashed into a taxi, which burst into flames. The Maserati, which had a passenger, struck another four cars, he said.

The drivers of the Maserati and the taxi were killed, as was a passenger in the taxi. The Maserati passenger and three others were taken to a hospital.

The incident was the latest in a series of violent actions on the tourist corridor since the beginning of the year.

Two people were critically wounded in a shooting at a parking garage February 6, and a tourist was stabbed in an

elevator at The Hotel at Mandalay Bay on Saturday.

There was no known motive for the shooting, police said.
