At least 16 people are dead and over 50 injured after two buses collided Wednesday in Khabarovsk region in Russia's far east. The accident occurred on the highway connecting Khabarovsk, the administrative center of Khabarovsk Krai.

Emergency personnel reportedly arrived at the site and rushed the injured to hospital. About 20 people are in serious condition, the Associated Press reported. The Investigative Committee has launched an investigation into the accident for possible traffic violations.

“The likely cause of the accident is speeding, since the road there is straight and well-maintained,” a police spokesman said, according to RT.com, which cited TASS news agency. “Experts will examine the crash site, look at the vehicles’ condition and determine the cause.”

The driver of one of the buses lost control after driving into an oncoming lane to avoid construction vehicles on the road, prosecutors reportedly said.

Last month, at least 11 people were killed after a bus and a truck collided in Krasnoyarsk region. Police reportedly seized the bus company's documents and the Investigative Committee opened two criminal cases over the accident.
