(CNN) -- The man who detonated a bomb at Domodedovo Airport in Moscow on Monday, killing 35 people, was a 20-year-old from the North Caucasus, the Russian Investigative Committee said Saturday.
The agency also said it was clear the bomb targeted foreigners.
"It was no accident that the terrorist attack took place in the international arrivals zone," the state-run RIA Novosti news agency quoted Investigative Committee spokesman Vladimir Markin as saying. "Investigators believe that it was directed against, in the first place, foreign nationals."
The bomb blew up in a crowded area of the international arrivals section, killing 35 people and wounding scores more.
