More confirmation, via AFP, that Moscow authorities will permit a march in memory of Nemtsov.
From our newsroom. We're trying to confirm the time, since that appears to be an hour earlier than previously reported.
The Moscow mayor's office granted permission to hold a march from Kitai Gorod to the Moscow City center on March 1.
Aleksei Mayorov, the head of the department for regional safety at the Moscow mayor's office, said the event would start at 2:00 p.m. local time and that permission was granted for up to 50,000 to take part.
Konstantin Merslikin, an official in Nemtsov's political party, says it is "99-percent sure" that Nemtsov's funeral will be held on March 3 at Moscow's Troyekurovsk Cemetery.
It appears that mourners will begin gathering at Kitai-Gorod at 2:00 p.m. on Sunday, with the memorial march itself to begin an hour later, at 3:00 p.m.
Our Russian Service correspondents spoke to Muscovites who went to the scene in the hours after the killing to lay flowers and remember Nemtsov. Here's an English version of some of those interviews:

Inside And Outside Russia, Condemnation Of Nemtsov Slaying
Nemtsov is being mourned in Kyiv, too. One of Russia's most urgent priorities, he suggested in an interview this past month with our Russian Service, was ending what he described as Russia's direct participation in the "war" in Ukraine. The antiwar message was one of the main rallying cries ahead of the planned march on Sunday.
