Fifteen people were killed on Sunday when a minibus collided with two trucks in the Ulyanovsk region of southern Russia, news agencies reported.
According to witnesses quoted by news agencies, a truck swerved off the road when it collided with a minibus traveling in the opposite direction near the village of Nikolayevka.
At the time of the accident, the minibus was also hit from behind by another truck. According to images broadcast by the Russian television channel Ren TV, the minibus was almost completely flattened by the two trucks.
The accident killed 15 people, all Kazakh citizens, the emergency services quoted by the Russian state agency RIA Novosti said.
Three other people – two men and a woman – were taken to hospital in serious condition, Ulyanovsk regional governor Alexei Ruskikh wrote on Telegram.
Violations of road safety rules are common in Russia, where several fatal bus crashes have occurred in recent years.
In January, five people were killed and 21 injured in a bus crash in the Ryazan region, about 270 kilometers (170 miles) south of Moscow.
In December 2019, a bus carrying around 40 passengers plunged into a frozen river in the Zabaykalsk region of Siberia, killing 19 people and injuring 21.
