At least 34 people were killed and 24 others injured on Saturday morning when a passenger bus turned turtle in Afghanistan's southern Kandahar province, a spokesman for local government said.

"A passenger bus was traveling from Kandahar province for capital city of Kabul, but the ill-fated bus turned turtle as it lost control on the highway in Daman district of Kandahar province in the wee hours Saturday. As a result some 34 people were killed and 24 others sustained injuries," Zalmai Ayubi told Xinhua.

Reckless driving on congested roads and highways is the main cause of road accidents in Afghanistan.

Ayubi also blamed the reckless driving for the incident, saying carelessness of the driver might led to the bloody accident and claimed the lives of innocent commuters.
