The lawyer said the lack of communication with Booth for two weeks

"I have not communicated with Booth for at least two weeks ... We have not yet been able to contact him," RIA Novosti quoted him as saying.

Earlier, Bout's wife Alla asked the Russian embassy in the United States to help her contact her husband, since communication with him was lost.

In June, the ombudsman for human rights in Russia, Tatyana Moskalkova, said that the issue of returning the Russians Viktor Bout and Konstantin Yaroshenko, convicted to the United States, was being discussed.
