AT least 30 people have been killed and 15 more injured after a bus tragically fell down a ravine in Bolivia.

The passenger bus is said to have lost control while speeding before plunging into a half-mile-deep abyss.

The accident happened on a narrow two-way road between the cities of Potosi and Oruro, with the route running along a ravine nearly half a mile deep.

At least 15 people injured in the crash — including three children — had been transferred to hospital, local news outlet Unitel reports.

Several were said to be in serious condition.

Authorities said that the crash was likely caused by speeding, with the driver “unable” to control the bus, according to Benavides.

It comes after 38 people were killed in a horror crash after a packed bus collided with a lorry in Brazil before bursting into flames.

The coach, carrying 45 passengers, caught on fire after one of its tyres suddenly blew out and sent the motor out of control, horrified witnesses said.

The driver battled to keep it on the road before it ploughed into an oncoming lorry.

Dozens of the passengers were ultimately killed along with the driver as the bus smashed off the concrete road.

Moments later the impact sparked a deadly inferno.

President Luiz Inacio Lula da Silva described the fatal smash as a “terrible tragedy” with harrowing images showing the burnt-out bus left on the side of the road.

It comes just months after three people were killed in a horrific bus crash carrying a Brazilian football team to a championship game.

Local media claims the trio who died were players from the American football team the Coritiba Crocodiles of the southern Brazilian city of Curitiba.

Meanwhile, seven people were killed and 15 injured after a luxury bus plunged into a 200ft gorge after slamming through a barrier.

The driver lost control and the vehicle, carrying 48 passengers, went through a crash barrier and fell about 35ft from the road.

Cops in Gujrat, India, said five people died instantly and 17 were taken to hospital with two later dying of their injuries.

Meanwhile, two people were killed in a horror bus crash on a busy German motorway.

Four others were seriously injured in the fatal smash after a coach carrying 14 passengers on a cross-country trip overturned and was left in a wreck on its side.
