Russia has launched a criminal inquiry against former executives of Moscow's Domodedovo Airport over loose security measures that allegedly facilitated the January 2011 terror attack at the airport.
Export Management Company head and director of the airport Svetlana Trishina, Domodedovo Airport aviation security director Andrey Danilov, and airport facilities director Vyacheslav Nekrasov, along with other non-established owners of the airport have been listed as suspects in the case.
The deadly attack at the airport located around 40km (25 miles) south-east of the city centre, was carried out by a suicide bomber, Magomed Yevloyev, in the international arrival hall.
Later Caucasus Emirate criminal group leader, Doku Umarov, claimed responsibility for the blast, which killed 37 people and injured 172 others.
One of the defense lawyers Igor Trunov has said that the attack was made possible by inadequate safety measures at the airport.
Russian Investigative Committee spokesman Vladimir Markin was quoted by Interfax as saying: "In the opinion of the detectives, actions of the aforesaid persons led to an increase in the airport vulnerability and civil aviation services which failed to meet security requirements.
"As a result, Magomed Yevloyev freely entered the terminal of the Domodedovo international airport with a bomb hidden under his clothes and set it off in January 2011."
All the three Domodedovo executives, if found guilty of negligence, would have to spend up to ten years in prison.
