A total of 12 people were killed and 46 others injured on Sunday when two buses collided on the border of the province of El Oued, 440 km southeast of the capital Algiers.
The accident occurred at around 2 a.m. local time (0100 GMT) on the road linking the provinces of El Oued and Biskra, said Ahmed Baoudji, director of Fire-fighting Department in El Oued.
This tragic accident was caused by overspeeding, he added.
The National Gendarmerie has opened an investigation to determine the circumstances of the accident.
On Saturday, Algerian National Road Safety Agency said 3,275 people were killed and 31,010 others injured in 22,507 road accidents across Algeria in 2019.
The Algerian Interior Ministry said recently that road accidents incurred an annual loss of 1 billion U.S. dollars to the public treasury.
