Moscow is considering retaliatory measures against the U.S. following the announcement of new sanctions on Russia, an official said Thursday.

Russian President Vladimir Putin's spokesman said Moscow regrets the new U.S. sanctions announced Thursday and will consider retaliatory measures, The Associated Press reported.

Dmitry Peskov, Putin's spokesman, said that the new sanctions are an example of President Obama's "unpredictable" and "aggressive foreign policy," according to the AP. He also claimed the new measures are aimed at trying to "deal a blow to the foreign policy plans" of President-elect Donald trump.

"Such steps of the U.S. administration that has three weeks left to work are aimed at two things: to further harm Russian-American ties, which are at a low point as it is, as well as, obviously, deal a blow on the foreign policy plans of the incoming administration of the president-elect," Peskov said.

Peskov said Putin had yet to study the new sanctions and work out the retaliatory measures Russia could take, the AP reported.

"For now I can not say what will be our response. Although, as we know, we have no other alternative than to abide by a principle of reciprocity. Naturally, we will issue an adequate response. This response will be formulated by the president of the Russian Federation," Peskov said, according to Ria News.

Vladimir Dzhabarov, the deputy chairman of the foreign policy committee in the Russian Duma, told the Russian News Agency TASS that "reciprocal steps" will be taken, adding, "The U.S. embassy in Moscow and, quite possibly, the consulates will be cut down to size as well."

The Russian Embassy in the U.S. also said that official statements and countermeasures will be annoucned Friday, citing Russian Foreign Ministry spokeswoman Maria Zakharova.

The Obama administration announced earlier Thursday it would expel 35 Russian intelligence operatives, shutter two Russian compounds in the U.S. and impose economic sanctions, diplomatic censure and public "naming and shaming" as retaliation against Russian hacking that was aimed at swaying the U.S. election.

Putin has denied responsibility for the hacks.

The sanctions include the broadening of a 2015 executive order to allow Obama to punish those involved in cyberattacks against the U.S.

The Treasury Department will now be allowed to freeze the assets of those who digitally damaged U.S. critical infrastructure.

The FBI and the Department of Homeland Security also released a report Thursday detailing how the Russian hacks occurred.
