A rally in Vancouver to show solidarity with Russia's opposition became heated as supporters of President Vladmir Putin crashed the event.

A Putin supporter identifying himself as Simon Spacewalker, says he came to the Vancouver Art Gallery to let Canadians know he doesn't support the conflict in Eastern Ukraine either, and according to him, neither does Putin.

Opposition supporter Irina Wirth said she can't believe the pro-Putin faction had the nerve to show up.

"I just couldn't hold it when I saw these outrageous slogans," said Wirth."They live in Canada, they take advantage of the Western lifestyle and they came here supporting Putin's regime."

The rally on the front of the steps of the Vancouver Art Gallery attracted about 100 people.

It was planned before the killing of opposition-leader Boris Nemtsov in Russia Friday night.

Nemtsov's death has raised tensions within and outside Russia.

The regime has suggested several motives for Nemtsov's killing including Islamic extremism, a provocation against the state staged by opponents, or reasons related to his personal life.

But Ukrainian President Petro Poroshenko said Nemtsov told him two weeks ago that he planned to publish proof of Russia's involvement in Ukraine's separatist conflict.

Tens of thousands of people marched through Central Moscow today mourning the well-known critic of the president.
