Kremlin critic Navalny says 'everything fine' in message from jail
His message was posted after his defence team visited him in the Kolchugino jail, where he is under quarantine.
Washington on Tuesday imposed penalties in a coordinated action with the European Union as US intelligence concluded that Moscow orchestrated the near fatal poisoning of jailed Kremlin critic Navalny in August.
In action coordinated with the European Union, President Joe Biden's administration renewed demands that Russia free Navalny, who has been sent to a notorious penal colony after spurring massive rallies through his allegations of corruption by President Vladimir Putin.
Citing two administration officials, CNN wrote that the United States will coordinate with the European Union to determine what the sanctions will entail and their exact timing.
The 44-year-old spent months recuperating from the near-fatal poisoning with the Soviet-era nerve agent Novichok that he claims was ordered by Putin - a claim the Kremlin has repeatedly denied.
President Vladimir Putin's most prominent opponent was sentenced this month to 2.5 years in a penal colony for breaching parole terms while in Germany recovering from a poisoning attack.
The move to target the Kremlin comes two weeks after EU foreign policy chief Josep Borrell was caught in a diplomatic ambush in Moscow that enraged member states.
A Moscow court was hearing Navalny's appeal against a decision this month to imprison him for nearly three years for violating the terms of a suspended sentence on embezzlement charges.
Putin suggested that the wave of protests recently held across Russia in the wake of Navalny's arrest and imprisonment had also been fed from abroad.
On Friday, Navalny was facing defamation charges for describing people who appeared in a pro-Kremlin video as 'the shame of the country' and 'traitors' in a June tweet.
Josep Borrell's visit to Russia is the first by a senior EU envoy since 2017 and follows terse exchanges between Moscow and the bloc whose ties have been deeply strained since the Kremlin annexed Crimea in 2014.
The EU's ties with Russia have been in the doldrums since Moscow seized Crimea and began fuelling the war in Ukraine in 2014 - and there are concerns about its involvement in Belarus, Syria, Libya, central Africa and the Caucasus.
Navalny, 44, was detained on January 17 when he returned to Moscow from Berlin, where he had spent months recovering from a poisoning attack in August he blamed on President Vladimir Putin.
On Sunday, thousands of protesters defied government warnings and rallied from Vladivostok to Saint Petersburg in a second weekend of mass demonstrations over the arrest of Alexei Navalny.
Russia's Interior Ministry said it had launched a criminal probe into the violation of sanitary and epidemiological measures during a Moscow protest that saw thousands rally in support of Alexei Navalny on Saturday.
Navalny's report - his most-watched anti-corruption probe by far - claims the property is worth $1.35 billion and features everything from an underground ice rink to a casino.
The investigation, published on the opposition figure's blog with an accompanying two-hour YouTube video recorded before his return to Russia, claims the property cost $1.35 billion and was paid for "with the largest bribe in history".
Police seized Alexei Navalny, President Vladimir Putin's most prominent opponent, at a border control post at Moscow's Sheremetyevo airport on Sunday.
President Vladimir Putin's most vocal critic was still waiting to see his lawyer hours after being taken away at border control following a flight from Germany where he was recovering after a near-deadly poisoning attack.
