MOSCOW (AP) American basketball star Brittney Griner went on trial Friday, 4 1/2 months after her arrest on charges of possessing cannabis oil while returning to play for a Russian team, in a case that unfolded amid tense relations between Moscow and Washington.

The Phoenix Mercury center and two-time U.S. Olympic gold medalist was arrested in February at Moscows Sheremetyevo Airport after police said she was carrying vape canisters with cannabis oil. She could face up to 10 years in prison if convicted of large-scale transportation of drugs.
