At least 31 people were killed and around 130 others in what authorities confirmed was a suicide bomb attack at Moscow's Domodedovo airport. Interfax cited officials as confirming that the attack was the work of a suicide bomber. Earlier, the Public Prosecutor's Office confirmed there had been an explosion but did not give the cause. The injured were being taken to at least four hospitals around the area. Earlier reports said the blast occurred in the baggage retrieval area of the arrivals hall at the airport, the Russian capital's biggest in terms of passenger traffic.
Authorities stopped all international flights to Domodedovo. Security was tightened at other Moscow airports and on the capital's underground rail system where a Chechen suicide bomber killed 40 people last year.
