Moscow, Dec 9 : Russian citizen Viktor Bout was exchanged for US basketball player Brittney Griner at the Abu Dhabi airport, the Russian Foreign Ministry announced. "Washington categorically refused a dialogue on the inclusion of Bout in the exchange scheme. Nevertheless, Russia continued to actively work to rescue our compatriot," the Ministry said in a statement on Telegram on Thursday. The US side has also confirmed the completion of the prisoners swap, Xinhua news agency reported. Griner was detained in February 2022 when she arrived at a Moscow airport from New York, after vape cartridges containing cannabis oil were found in her luggage. In August, she was sentenced to nine years in prison and fined one million rubles ($15,773) for drug smuggling. At the request of Washington, Thai police arrested Bout in Bangkok in 2008 for selling weapons to a US-designated foreign terrorist group. He was extradited to the US in 2010 and sentenced to 25 years behind bars with a fine of $15 million in 2012. /IANS
