Three people have died and at least three others were injured after a "rolling" gun fight and crash involving several cars in Las Vegas, police say.
Five vehicles were involved in the crash - including a taxi that burst into flames - at a crossroads on the busy Las Vegas Strip.
The occupants of a Maserati and SUV were exchanging gunfire before the Maserati hit the taxi.
The three killed were the Maserati driver, taxi driver and taxi passenger.
A passenger from the Maserati and two others were taken to hospital.
Police are still searching for the SUV, which had gone by the time police arrived at the scene. It has been described as a black Range Rover Sport with large black wheel rims.
The incident occurred at about 04:30 local time (12:30 GMT) at the junction of Flamingo and Las Vegas boulevards, police sergeant John Sheahan said.
The moving cars were already shooting at each other when the Maserati collided with the taxi, Sgt Sheahan said.
The site of the crash is in the centre of downtown Las Vegas, next to the Bellagio hotel and casino, with its famous fountains.
The central location can be busy at all times, Las Vegas police officer Jose Hernandez told CNN.
Police say it is possible that other people might have been hurt.
It is the third incident of violent crime to hit the popular casino resort this month.
Two people were wounded in a shooting at a Las Vegas car park on 6 February.
And a tourist was stabbed in a lift at the city's Hotel Mandalay Bay on 16 February.
