Tolyatti bus bombing

On the morning of 31 October 2007, a bomb detonated aboard a passenger bus near a bus stop in the city center of Tolyatti, a city in Samara Oblast, Russia. The explosion occurred during rush hour as commuters were traveling to work. At least eight people were killed and approximately 50 others were injured in the blast.

Irina Doroshenko, a spokeswoman for the investigative wing of the local prosecutor's office, stated that the explosion could have been a terrorist attack. In the initial phase of the investigation, authorities believed the bombing was the work of terrorists linked to the North Caucasian Federal District. Early reporting also raised the possibility of involvement by Chechen figure Doku Umarov.

However, officials later revised their assessment, naming a 21-year-old individual, Evgeny Vakhrushev, as the person responsible for the bombing. Vakhrushev also died in the blast. According to the available account, officials concluded he was the only person responsible for the tragedy.
