Moscow explosion: Experts say the explosion, which killed at least 35, will likely be traced to Russia's volatile north Caucasus region, where political murders, bombings, and kidnappings occur almost daily.

A huge blast, reportedly triggered by a suicide bomber, hit Moscow's busiest airport Monday afternoon, killing at least 35 people and injuring over 130.
The bomb, which Russian news agencies said was equivalent to seven kilograms (15.4 pounds) of TNT, went off just after 3 p.m. in the crowded arrivals area of Domodedovo airport. Domodedovo is used as a Russia gateway by British Airways, Lufthansa, Cathay Pacific, El Al, and many airlines of former Soviet countries.
The domestic section of Domodedovo is the main arrival point for flights from Russia's troubled southern regions, including the north Cacasus.
A 'knot' of problems in north Caucasus
A high-ranking Russian security official told the independent Interfax agency that the explosion was caused by "terrorism," possibly originating in a flight from the north Caucasus.
