Russian authorities have revealed the name of a suspected suicide bomber of a Moscow airport last month and arrested his relatives.

Magomed Yevloyev (20), a native of the North Caucasus region of Ingushetia that neighbours war-torn Chechnya, was identified as the man who blew himself up in the international arrivals of the Domodedovo airport on January 24, killing 36 and wounding 180 people. The man's identity was established through DNA tests.

Police arrested Yevloyev's suspected accomplices — his 16-year-old brother Akhmed, 22-year-old sister Fatima and a friend. Tests showed they had traces of explosives on their hands. Another two men who helped stage the attack have been put on a wanted list.

Yevloyev, long-time unemployed, joined a rebel group two weeks after police killed his sister's husband, an Islamic militant.

Chechen warlord Doku Umarov, who had taken credit for blowing up the Moscow metro last year, claimed responsibility for the Domodedovo bombing as well, vowing to make 2011 a “year of blood and tears” for Russia.
