"Venezuela is friendly to us and is our strategic partner," Vladimir Putin's deputy foreign minister said. "We have supported them and will support them."
MOSCOW — Russia warned the U.S. on Thursday not to intervene militarily in Venezuela, saying such a move would trigger a catastrophe.
Venezuelan opposition leader Juan Guaido declared himself interim president on Wednesday, winning the backing of Washington and prompting socialist incumbent Nicolas Maduro to sever diplomatic relations with the United States. Violence flared during big protests across Venezuela, and at least seven deaths were reported.
In an interview with Russian journal International Affairs published on Thursday, Deputy Foreign Minister Sergei Ryabkov said Moscow would stand with Venezuela to protect its sovereignty and the principle of non-interference in its domestic affairs.
Asked about the prospect of U.S. military intervention in Venezuela, Ryabkov said Washington should steer well clear.
"We warn against that," he said. "We consider that would be a catastrophic scenario that would shake the foundations of the development model which we see in Latin America."
President Donald Trump has promised to use the "full weight" of U.S. economic and diplomatic power to push for the restoration of Venezuela's democracy.
The prospect of Maduro being ousted is a geopolitical and economic headache for Moscow which, alongside China, has become a lender of last resort for Caracas, lending it billions of dollars as its economy implodes. Millions of people have fled the country in recent years to escape sky-high inflation and food shortages.
