Alexei Navalny's wife says she will reveal names and faces of husband's killers

The widow of late Russian opposition leader Alexei Navalny, Yulia Navalnaya, released a video on Monday where she claimed “we know why exactly Putin killed Alexei three days ago, we will tell you about it soon," adding "we will name names and show faces.”

Navalnaya was in Brussels Monday and is expected to meet with European Union foreign ministers and other EU officials.

On Sunday, she published a picture of the couple on Instagram in her first social media post since her husband’s death, with the caption “I love you.”

Navalny’s death has deprived the Russian opposition of its most well-known and inspiring politician less than a month before an election that is all but certain to give Putin another six years in power.

It dealt a devastating blow to many Russians, who had seen Navalny as a hope for political change following his unrelenting criticism of the Kremlin.
