A US soldier detained in Russia has been accused by state prosecutors of threatening to kill his girlfriend.
Staff Sergeant Gordon D. Black was originally arrested close to the Russia-North Korea border on May 2 on suspicion of theft, but the charges against him have been toughened.
Black, 34, had followed Alexandra Vaschuk - also known as Aleksa Viktorovna, 31 - from South Korea, where he was posted by the US army, to her home city Vladivostok, a Russian Pacific naval port.
According to the indictment, Black “grabbed the woman by the neck” during a quarrel.
The Primorsky region prosecution service said: “He is charged with a threat of murder with grounds to fear the threat might be fulfilled, and a theft inflicting considerable damage."

State news agency Interfax reported: “The woman said she took his actions as a threat to her life.
“After that, Black, who had no money of his own, stole 10,000 rubles [£88] from the woman's wallet and spent it on his needs, including a hotel room where he was found and detained.”
Earlier reports specified he had stolen a much higher amount - 200,000 rubles (£1,765) plus alcohol.
Black was taken into detention earlier this month and has been ordered to remain in a pre-trial detention until a new custody hearing in early July.
The charges he faces both carry sentences of up to two years.
The threat to kill charge under certain circumstances may carry a maximum five-year sentence.
There is evidence the US serviceman was planning to leave Vladivostok when he was detained as he had reportedly bought a flight ticket.
The Russian woman - who has been pictured with a gun - is known to have lived in South Korea previously, and this appears to be where they met and started a “romantic relationship”.
Pictures showed them enjoying meals out together in January and earlier.
Russian reports earlier stated that two weeks after coming to Vladivostok the US Army staff sergeant - who is reported to be married - “beat his beloved and stole 200,000 roubles from her”.

Russian foreign ministry officials earlier said the case is "not related to politics or espionage”.
It is believed Black underwent lengthy questioning from the Russian authorities when he arrived in the country, but was then allowed to enter.
There are reports in Russia that the pair had known each other for several years.
A US army spokeswoman said following his detention: "The Army notified his family and the U.S. Department of State is providing appropriate consular support to the soldier in Russia.”
The soldier, from Red Bud, Illinois had been expected back in Texas for a new posting.
Black's mother, Melody Jones, told the US media her son had gone to Russia to visit his girlfriend.
The Russian Interior Ministry said today that the woman had met Black in Korea where she worked and that they were “in a relationship”.
“On 10 April, the man came to the acquaintance's house in the Far Eastern capital,” said the statement.
“Later, the applicant had a conflict with the acquaintance at home.
“After he left, the woman discovered that the money was missing and turned to the police for help.
“Police officers found the suspect in one of the city hotels. He had purchased air tickets and intended to fly home.”
The arrest comes amid suspicions that Russia is seeking to hold US citizens to be used as bargaining chips to secure the release of Russians convicted abroad.
