The U.S. has urged Moscow to accept a deal to free basketball player Brittney Griner, who has been sentenced to nine years in a Russian prison, the BBC reports.
The double Olympic winner was convicted of possessing and smuggling drugs after admitting to possessing cannabis oil.
White House national security spokesman John Kirby said the U.S. offer was “a serious proposal,” but gave no details.
U.S. media reports suggest Washington is offering a prisoner swap involving a Russian arms trafficker. Viktor Bout — known as the “merchant of death” — is serving a 25-year prison sentence in the U.S.
He could be transferred by Washington to the Russian authorities in exchange for Griner and former U.S. Marine Paul Whelan, the reports say.
Whelan, who has U.S., British, Canadian, and Irish passports, was sentenced in 2020 to 16 years in jail in Russia after being convicted of spying.
Kirby told reporters that the two were being wrongfully detained and needed to be let go.
On the subject of the U.S. proposal, Kirby said: “We urge them to accept it. They should have accepted it weeks ago when we first made it.”
But according to Reuters news agency, one stumbling block is that Russia wants to add convicted murderer Vadim Krasikov, who is in prison in Germany, to the proposed swap.
When questioned about this possibility, Kirby dismissed it, saying: “I don’t think we go so far as to even call it a counter-offer.”
Griner, 31, told the court she had made an “honest mistake” and had not intended to break the law.
Considered one of the best female players in the world, she was detained in February at an airport near Moscow when vape cartridges containing cannabis oil were found in her luggage. She had come to Russia to play club basketball during the U.S. off-season.
Soon afterward, Russia invaded Ukraine and her case has become subject to high-profile diplomacy between the U.S. and Russia.
Her defence team said they would appeal the verdict.
Griner’s Phoenix Mercury teammates staged a gesture of solidarity on Thursday, when they and their Connecticut Sun opponents observed 42 seconds of silence before their game, in honour of her number 42 jersey.
President Joe Biden called her sentencing “unacceptable”, adding: “I call on Russia to release her immediately so she can be with her wife, loved ones, friends, and teammates.”
Meanwhile Secretary of State Antony Blinken added: “Russia, and any country engaging in wrongful detention, represents a threat to the safety of everyone travelling, working and living abroad.”
Blinken raised the issue in a phone call with Russian Foreign Minister Sergei Lavrov last week, in the first conversation between the two men since the start of the war in Ukraine.
Both are in Cambodia for a meeting of the Association of South-East Asian Nations. The U.S. says Blinken will try to speak with Lavrov again while they are there.
