Russia's American embassy demanded that the United States return diplomatic compounds seized by the Obama administration amid spying accusations last year, warning that it would retaliate if America refuses.

The embassy's official Twitter levied the threat along with a picture that appears to be of Americans at a U.S. compound in Moscow.

"If Washington fails to restore diplomatic immunity of [Russian] property there will be a tit-for-tat response in regard to U.S. facilities in Russia," the tweet reads.

America seized and shuttered two Russian compounds in Maryland and New York last December in retribution for revelations that Russians hacked and released internal communications by the Democratic National Committee in an attempt to destabilize the presidential election. Then-President Obama accused the Russians at the time of using the two compounds for "intelligence-related purposes."

The administration also expelled 35 Russians accused by the administration of being "intelligence operatives."

The Russians did not immediately retaliate, instead releasing a statement that dismissed the Obama administration and said the country would wait until then-President-elect Trump took office.

Trump praised that "great move on delay (by V. Putin)" soon after.

But the fate of the compounds has clearly been an important sticking point in the relations between the Russian and American governments. Sergey Kislyak, the Russian ambassador to the United States who was found to have had undisclosed communications with Trump allies, told Buzzfeed this week that he brings the issue up "each and every day."
