Moscow demanded on Saturday that authorities in Estonia, Latvia and Lithuania take measures to protect Russia's embassies after a Russian diplomat was attacked in the Lithuanian capital Vilnius, the Russian RIA news agency said.
"We are warning Vilnius, Riga and Tallinn that they are responsible for the consequences of the anti-Russian psychosis they have unleashed," the Russian foreign ministry was quoted as saying.
"A Russian diplomat in the Lithuanian capital was attacked with the use of physical force, attempts were made to put pressure on the Ambassador," it added.
A spokesperson for Lithuanian police told Reuters no incidents involving Russian embassy staff were reported on either Friday or Saturday.
