Three of the four defendants in the 2011 bombing of Moscow's Domodedovo airport have been sentenced to life in prison.
The Moscow Regional Court found brothers Islam and Ilez Yandiev, Bashir Khamkhoev, and Akhmed Yevloev guilty of terrorism, murder, banditry, and other charges.
The Yandiev brothers and Khamkhoev received life sentences; Yevloev received a 10-year prison sentence. Yevloev, the brother of the Domodedovo bomber, said he had no knowledge of his brother Magomed's plans.
Khamkhoev complained his guilt was not proven at the trial.
On January 24, 2011, Magomed Yevloev detonated explosives inside Domodyedovo airport, killing himself and 37 other people and wounding 172. Investigators say Chechen rebel leader Doku Umarov masterminded the attack.
