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)

Ukraine to be topic of EU talks in Riga today:
The Ukraine conflict is high on the agenda of two days of informal talks between European Union foreign ministers who are gathering in Latvia’s capital, Riga, on March 6.
According to officials in Latvia, which currently chairs the EU Council, the talks will focus on the conflict in Ukraine -- including tensions between the EU and Russia over Moscow's deployments of troops and weaponry there, and the implementation of the Minsk cease-fire agreements for eastern Ukraine.
On the eve of the gathering, European foreign policy chief Federica Mogherini said the ministers would consider additional sanctions against Russia over its support for separatists in eastern Ukraine.
Maja Kocijancic, spokeswoman for EU foreign policy chief Federica Mogherini, said ministers from the 28 EU member countries also would discuss the possible use of international peacekeepers in Ukraine.
Also on the agenda are preparations for the EU’s Eastern Partnership summit in May.
