The Russian Investigative Committee has completed a criminal inquiry into the terrorist attack at Moscow's Domodedovo Airport, Investigative Committee spokesman Vladimir Markin told Interfax.
"The investigation is completed, the case materials have been sent to the Prosecutor General's Office for approval of the indictment," Markin said.
There are four defendants in the case: the brothers Islam and Ileza Yandiyevs, Akhmed Yevloyev and Bashir Khamkhoyev, Markin said.
They are being charged with membership in a criminal group, membership in a permanent armed group and its attacks, committing a terrorist attack, an attempted terrorist attack, murder, attempted murder, illicit arms trafficking and illegal arms manufacture, Markin said.
According to the inquiry, 21-year-old Magomed Yevloyev detonated an improvised explosive device attached to his body, with a weight equivalent to between three and five kilograms of TNT, filled with shrapnel in the form of multiple cylindrical rollers and ball bearings, at the international arrivals section at Domodedovo Airport on January 24, 2011.
The explosion killed 37 people and injured 172 Russian and foreign citizens.
According to investigators, the terror attack was organized by leader of the Caucasus Emirate criminal organization, Doku Umarov, who supervised a gang led by Aslan Byutukayev and Supyan Abdullayev, who chose and trained Yevloyev for the suicide bomb attack.
"The gang consisted of about 35 people," Markin said.
On March 28, 2011, a militant camp was eliminated and 17 militants killed on the spot as a result of a special operation in Ingushetia.
In all, search and investigative procedures led to the identification of 28 members of the criminal organization, the Caucasus Emirate, who were involved in organizing and committing the terror attack at Domodedovo. Four were arrested and remanded in custody.
The criminal investigation of the case against suspected organizers of the terrorist attack at Domodedovo Airport, including Umarov, Byutukayev and others, continues.
