Ukrainian Nemtsov witness says receiving threats:
Ukrainian authorities say they have opened a criminal investigation after a key witness in the killing of Russian opposition politician Boris Nemtsov said she had received threats.
Anna Durytska, a 23-year-old Ukrainian model, was with Nemtsov when he was shot dead in central Moscow on February 27.
The Ukrainian Prosecutor-General's Office said on March 6 that Durytska told Kyiv police she had received death threats from unknown people.
It said Prosecutor-General Viktor Shokin had ordered that "all necessary measures are taken to protect the life and health" of Durytska.
A spokesman for the Prosecutor-General Office Andriy Demartyno told AFP news agency that several "police special forces officers" will ensure her safety.
Durytska said on March 3 that she did not see Nemtsov's killer, and could not make out the model or license plate number of a car she saw near the scene. (AFP, Interfax, UNIAN)
