     Anna Duritskaya, the companion of Russian opposition leader Boris Nemtsov when he was shot on a Moscow bridge, has arrived back in Ukraine. She had earlier complained of being barred from leaving Russia.

Duritskaya flew into an international airport in the Ukrainian capital, Kyiv, late on Monday, and was quickly whisked away in a car with blacked-out windows.

The 23-year-old Ukrainian, who had been walking with Nemtsov when he was mysteriously killed on Friday, shot with a Makarov pistol, was accompanied on the plane journey by her lawyer, Vadim Prokhorov.

Prokhorov told reporters his client - who had complained previously that she was being prevented from leaving Moscow - needed to rest. The lawyer said Duritskaya had been left "emotionally drained" by investigators' questioning.

"She has given a full and exhaustive account of her last hours with Boris," Prokhorov said. "If any further investigative action is required, she has promised - something she has done publicly - that she will cooperate. The main thing is that the guilty parties be tracked down."
