NATO allies 'stand' with US on Russia sanctions
"Allies are taking actions individually and collectively to enhance the Alliance's collective security," it said.
NATO members cited a "sustained pattern" of Russian behaviour, from aggression against Ukraine to interference in the US presidential election and cyber attacks.
"The United States and other Allies assess that all available evidence points to the responsibility of the Russian Federation for the SolarWinds hack," the statement said.
The alliance also condemned the nerve agent attack on Kremlin critic Alexei Navalny, which it blames on Moscow, and said it was concerned by reports Russia had encouraged attacks againsts its troops in Afghanistan.
"Allies will continue to work in close consultation to address Russia's actions, which constitute a threat to Euro-Atlantic security," the statement said.
"We call on Russia to cease immediately its destabilising behaviour, and to uphold its international obligations."
The US announced economic sanctions against Russia on Thursday and the expulsion of 10 diplomats in retaliation for what Washington says is the Kremlin's US election interference, a massive cyber attack and other hostile activity.
President Joe Biden's executive order "sends a signal that the United States will impose costs in a strategic and economically impactful manner on Russia if it continues or escalates its destabilising international action," the White House said.
