Strong editorial by The Guardian:
Amid the various narratives of “the truth” now being rehearsed by the Russian state, it is necessary to insist upon a reality; on Friday morning Mr Nemtsov was alive, but by the day’s end he was dead. Amid the mischievous misdirection of the Kremlin’s counter-measures, this is, quite simply, the truth.
Our Moscow correspondent Tom Balmforth, speaks to Ilya Vaitsman, 42, an engineer who traveled to the wake from Nizhny Novgorod.
"I've known him since [his days] in Nizhny Novgorod," he says. "I think things are going to get worse in the country without him."
Nemtsov served as governor of Nizhny Novgorod in the 1990s, before being promoted by then-President Boris Yeltsin to deputy prime minister.
"Massovka" is slang for a group of people paid to demonstrate. The tactic is frequently used by people friendly to the Kremlin.
In the red jacket is Aleksey Venediktov, chief editor of the liberal Echo Moskvy radio station, and to his right is John Tefft, the U.S. Ambassador to Russia.
Our Russian Service is providing a live feed of Nemtsov's memorial.
Deputy Prime Minister Arkady Dvorkovich spotted by Dozhd TV. He may be the highest-level member of the Russian government there.
Reports of long lines for the memorial service, which is set to start in 15 minutes.
