At least 35 people were killed and about 130 injured on Monday in a suicide bombing at Russia’s biggest airport, state-run TV reported.
The blast ripped through the arrival hall of Domodedovo airport, Russia’s largest airhub, the airport’s press office said in a statement.
Airport employees broke down a wall between the main airport and the arrival zone to allow passengers to escape from the scene of destruction, a news agency said.
Investigators said the bomb had been classified as a terrorist attack — the first of its kind in the Russian heartland this year.
Russian President Dmitry Medvedev, too, said "from the preliminary information we have, it was a terror attack".
Analysts said that rebels waging an Islamist insurgency in Russia’s mainly Muslim North Caucasus (border region north of the Caucasus mountains) were planning to increase their violent campaign in the Russian heartland in 2011 as the
country prepares for the 2012 presidential elections.
Security has been beefed up at Moscow’s other two airports, officials said.
Moscow suffered its worst attack in six years in March 2010 when two female suicide bombers from the volatile Dagestan region set off explosives in the metro, killing 40 people.
