At least 13 have been killed and dozens injured after a bus carrying Chinese tourists skidded off the road and fell into a 30-metre-deep ravine in Laos, according to the police.
Police officer Xaiyaphon Chitavong has told AFP that a brake failure could have been the cause of the accident.
"At this moment, 13 bodies have been recovered... while two are still missing", the officer said as quoted by AFP.
Some 31 people are currently receiving medical assistance.
From June to October is the monsoon season in Laos with heavy rain showers creating slippery conditions on rural roads.
