The Russian Mission to the US released photos of the closed diplomatic facilities without Russian state flags Wednesday.

“A strong objection was sent to the American side in the wake of the removal of Russian flags from the diplomatic property in San Francisco, controlled by the US authorities. We perceive it as an extremely unfriendly move. We demand [the US] immediately returns the Russian state symbols to their place and prevents such incidents in the future,” the embassy said in a statement on Facebook.

“Yet another one disgraceful event. Flags have been stolen from the buildings in San Francisco. We urge the US authorities to return our state symbols,” the embassy added in a Twitter post.
