Russian authorities have named a suspected suicide bomber of Moscow's airport and arrested his teenage brother and sister.
An official with Russia's top investigative agency in the province of Ingushetia said Wednesday that the Jan. 24 bombing of Domodedovo airport was conducted by Magomed Yevloyev, 20. He spoke on condition of anonymity because he wasn't authorized to publicly discuss the issue.
The official said that on Tuesday a court in Ingushetia ordered the arrest of Yevloyev's 15-year old brother and the 16-year old sister, who are suspected of involvement in the attack.
Officials have previously said that the bomber was a 20-year old man from the Caucasus, but didn't give his name.
Chechen rebel warlord Doku Umarov has claimed responsibility for the attack that killed 36.
