From the U.S. ambassador to Ukraine:
Vedomosti has more (in Russian) on the major demonstration and concert that are to be held outside the Kremlin, very near the scene of Nemtsov's killing, on March 18, marking the first anniversary of what Moscow dubs the "reunification" with Crimea, forcibly annexed from Ukraine.
Via the Reuters Live feed, EU foreign affairs chief Federica Mogherini speaking at a joint news conference with Latvian Foreign Minister Edgars Rinkevics during the EU foreign ministers meeting in Riga:
"We have to obviously be very realistic about the developments in the Russian attitude starting from the illegal annexation of Crimea last year and we are approaching the anniversary in one week of a very bad development. But we also have the duty to exercise our role, which is also a role of looking all the time for a political channel in the interest first of all of our eastern partners, be it Ukraine, be it Moldova and Georgia, be it other partners."
"The European Union today is extremely realistic about the developments in Russia but will never be trapped or forced or pushed or pulled into a confrontative attitude, we still believe that around our continent, not only in our continent, but around our continent cooperation is far better than confrontation and we still argue for that."
