NEW YORK: The WNBA said on Thursday it was working with the U.S. government to get All-Star Brittney Griner freed from a Russian prison after the TASS news agency said her detention for possession of vape cartridges containing hash oil was extended until May 19.

TASS said the Khimkinsky court of the Moscow region ruled to detain the 31-year-old Griner, who was arrested last month, for at least two more months.

Her detention comes at a time of high tension between the United States and Russia following Russia's invasion of Ukraine.

"This continues to be a complex situation that is extremely difficult for Brittney, her family, and all who are hoping for a swift resolution," the WNBA said in a statement. "Our number one priority remains her safe return."

"In close collaboration with U.S. government agencies, elected officials, individuals and organizations with expertise in these matters, and Brittney Griner’s representatives and family, we continue to work diligently to get her safely home to the United States."

The U.S. State Department said it is working on the case and is in contact with Griner's legal team. Officials are working on gaining consular access to all U.S. citizens detained in Russia, including those in pre-trial detention, a State Department spokesperson said.

"We have repeatedly asked for consular access to these detainees and have consistently been denied access," the spokesperson told Reuters.

"Russia must abide by its legal obligations and allow us to provide consular services for U.S. citizens detained in Russia."

LEGAL MATTER

Representatives for Griner referred Reuters to a previous statement indicating they would not comment on the specifics of an ongoing legal matter.

Griner won Olympic gold medals with the U.S. national teams in 2016 and 2021 and is a seven-times All-Star. She plays centre for the Phoenix Mercury team, and plays in Russia during the WNBA's winter off-season.

The new WNBA regular season starts on May 6.

TASS reported that Griner was sharing a cell with two other women with no previous convictions, adding that her only issue was that the prison beds were too short for her 6'7" frame.

The Russian Customs Service said this month that a player was detained in February after arriving at Moscow's Sheremetyevo airport on a flight from New York. 

TASS identified the player as Griner, citing a source.

A scan of the player's luggage revealed cartridges containing "liquid with hashish oil", and a criminal case has been opened carrying a possible sentence of five to 10 years in prison, the customs service said.

It was not clear exactly when Griner was detained but it was announced after Russia's invasion of Ukraine on Feb. 24.

The invasion has dramatically worsened relations between Washington and Moscow, and U.S. President Joe Biden this week called Russian leader Vladimir Putin a war criminal.

Russia calls its actions in Ukraine a "special operation" designed not to occupy territory but to destroy its neighbour's military capabilities and capture what it regards as dangerous nationalists.

U.S. Secretary of State Antony Blinken said this week that the Biden administration had assigned an embassy team to work on Griner's case.
