Russian officials say two suspects in the suicide bombing at the country's busiest airport have been seized in an operation in which 17 insurgents and three security officers were killed.
The Monday raid included air and ground strikes against an encampment in Ingushetia, one of the republics in Russia's Caucasus region plagued by separatist violence and crime.
A spokesman for the Interior Ministry for Russia's southern region, Sergei Morozov, said two Federal Security Service officers and a policeman also died in the operation.
Morozov said two suspects in the Jan. 24 bombing of Domodedovo Airport were arrested. It was not immediately clear how what connection they may have had to the bombing that killed 37 people. A Caucasus rebel leader claimed responsibility for organizing the bombing.
