At least 24 people were killed and dozens injured after a bus plunged into a ravine in Indonesia on Monday, according to police.

The accident took place in a remote and steep area near the town of Pagar Alam, hampering the efforts to rescue the victims.

Earlier on Tuesday, local police spokesman Dolly Gumara, the bus carrying dozens of passengers carried into a 150-metre ravine in South Sumatra province just ended up in a river.

“It crashed into the concrete road barrier before plunging into the ravine. Some people are still trapped inside the bus,” Gumara added.

“No other vehicle was involved”, Gumara further noted.

Search and rescue teams have been deployed to look for victims, Gumara said, adding injured survivors were taken to hospital.

“Some passengers were probably added along the way so there’s a possibility some more people are still missing in the river,” Gumara said.

Traffic accidents are common in the Southeast Asian archipelago, where vehicles are often old and poorly maintained and road rules regularly flouted.

In September, at least 21 people died when a bus plunged into a ravine in West Java’s Sukabumi region.

Earlier, 12 people were killed and dozens more injured after a passenger tried to wrest control of a bus steering wheel following an argument with the driver on the same toll road in West Java.

The bus smashed into two cars that caused a truck to roll.
