Hundreds are converging in Moscow for the funeral of Alexei Navalny, Russian opposition leader.
Navalny died in the Arctic Prison colony where he was serving a 19-year sentence.
Police presence is heavy in the city with masked guards stationed around a perimeter fence.
The people who have converged are aware they risk arrest by attending and showing support for a well-known critic of the government.
According to the bbc.com:
A number of foreign dignitaries, including the US ambassador were seen near the church.
Few details have been released on the cause of his death – officials say he collapsed after going for a walk.
