Chechen militant says he ordered Russia bombing
A Chechen islamic militant, Doku Umarov, has claimed responsibility for last month's deadly suicide bombing of Russia's largest airport.
The attack at Domodedovo, in Moscow, left 36 people dead, including British, German and Ukrainian travellers.
Umarov and the rebels that he leads want to create an independent emirate, governed by Sharia law, in Russia's Caucasus region.
