MOSCOW -- Hundreds of Russians honored slain opposition leader Boris Nemtsov on the bridge in Moscow where he was gunned down 40 days ago.
It's a Russian Orthodox tradition to honor the deceased 40 days after the death. Nemtsov, a vocal critic of President Vladimir Putin, was memorialized with flowers, photos and signs.
People also observed a "minute of non-silence" at 11 a.m., whistling or honking their car horns.
Nemstov was murdered just before midnight on Feb. 27 just steps from the Kremlin. Five suspects from the North Caucasus have been arrested.

Investigators have suggested the men, who they described as radical Islamists, were motivated by Nemtsov's support for the French magazine Charlie Hebdo. The men have denied involvement.
Nemtsov's supporters have been more skeptical about the motive for the murder, saying authorities should focus their effort on whomever was behind it.
