Details are scarce at the moment, but, according to Reuters, at least 31 people were killed at Domodedovo Airport and another 100 were injured from a suicide bombing at Russia’s largest airport.
Smoke wafted out of the baggage claim area and people were seen running out of the emergency exits at the airport, local media reported.
Initial casualty figures were contradictory with ITAR-TASS saying about 20 people had been killed. A spokeswoman for prosecutors put the number of casualties at about 20.
Moscow suffered its worst attack in six years in March 2010 when two female suicide bombers from Russia’s volatile Dagestan region set off explosives in the metro, killing 40 people.
The Kremlin is struggling to contain an Islamist insurgency in the mainly Muslim North Caucasus, and rebels have repeatedly vowed they will take their battle to the Russian heartland.
