国际英语新闻：Two suicide bombers involved in Moscow airport attack: source

MOSCOW, Jan. 25 (Xinhua) -- Two terrorists were involved in the suicide bomb attack at Moscow's Domodedovo airport on Monday, a law enforcement source told local media Tuesday.

Both suicide bombers died in the explosion that killed 35 people and injured over 130 others, the source said.

"The blast occurred when a suspected female terrorist opened a bag. She was accompanied by a man whose head was ripped off by the explosion," the source told RIA Novosti news agency.

He said it was possible that they wanted to leave the explosive in the hall but the bomb was detonated inadvertently or by a remote control.

"The attack was done according to a scheme that is used by terrorists from the North Caucasus region," he said, recalling that the Moscow metro blasts in March 2010 were carried out in a similar way.

The Russian Emergency Situations Ministry has published a preliminary name list of those killed in the attack, including eight foreigners, Interfax news agency reported.

Russian President Dmitry Medvedev said on Tuesday that the officials of the airport should be held responsible for security violations.

"What happened exposes evident violations of security regulations. It is not so easy to carry such a large amount of explosives (inside the airport). Everyone who has anything to do with the company, who is in charge of making decisions there, as well as the management of the airport should be held to account for it," Medvedev said.

"This is a terrorist attack, this is a disaster, and this is a tragedy," the president was quoted as saying in an interview with the Vedomosti newspaper.
