Russia's foreign ministry has summoned the Canadian ambassador and issued a protest over attacks on the Russian embassy in Ottawa, the ministry said on Monday.
It said an unknown person threw a Molotov cocktail - gasoline bomb - onto the grounds of the Russian embassy in Ottawa. It also said "aggressive" demonstrators had blocked an entrance to the consular section of the embassy.
A spokesperson for Canadian Foreign Minister Melanie Joly said violence and vandalism are not acceptable, and relevant authorities were looking into the matter.
