Chechen rebel leader Doku Umarov has said his group was behind Monday’s double suicide bombings on the Moscow Metro, which left 39 people dead.
In a video message posted on a Chechen rebel website, he said he had personally ordered the attacks.
He said they were carried out in retaliation for the killings of “poor Chechen and Ingush residents” by the Russian security forces in February.
Doku Umarov also warned Russia to prepare for more attacks.
