Kremlin spokesman Dmitry Peskov told reporters in a conference call that the Kremlin was closely studying the impact on Russian markets of sanctions imposed by Washington on Friday, Reuters reported.
Peskov said the sanctions were "egregious from the point of view of legality and disrespect for norms."
The United States imposed major sanctions on Friday against Russian businessmen, companies and government officials, striking at allies of President Vladimir Putin in one of Washington's most aggressive moves to punish Moscow for its alleged meddling in the 2016 US election and other "malign activity."
