Members of the lower house of the Russian parliament, the State Duma, will hold a session on Tuesday to discuss an ongoing investigation into a recent terrorist attack on Moscow`s Domodedovo airport. State Duma Speaker Boris Gryzlov said on Monday that eight top police, security and transport officials had been invited to attend the "behind-the-closed-doors" session and deliver reports on the progress of the investigation. Gryzlov added that the reports would help the lawmakers to decide how the legislation should be changed to ensure security of Russian citizens, including on transport. A powerful blast that ripped through the international arrivals hall of Russia`s largest airport on January 24 killed 36 people and injured 180. The explosive device was detonated by a suicide-bomber who had been reportedly under the influence of a "massive amount" of drugs and "psychotropic substances." No group has yet taken responsibility for the attack, which came less than 12 months after two female suicide bombers from the North Caucasus republic of Dagestan struck the Moscow metro, killing dozens.
