Russian President Vladimir Putin on Monday urged Moscow's 12 million residents to respect a strict new lockdown, as other parts of the country began to introduce similar steps to curb the coronavirus outbreak.
The enforcement of the new rules, which Moscow Mayor Sergei Sobyanin suddenly announced late Sunday, coincided with the beginning of a "non-working" week Putin declared last week.
"I ask you to take these forced but absolutely necessary measures... very seriously and completely responsibly," Putin told Muscovites.
The capital has become the epicentre of the contagion in Russia, and Mayor Sergei Sobyanin's new rules allow only trips to buy essential goods, go to hospital, to take out the rubbish or walk pets.
The Red Square in the heart of Moscow was eerily empty, and the streets of Europe's most populous city quiet, though traffic could still be seen on the roads.
Police cars drove slowly through the streets,on the lookout for Muscovites breaking the rules.
Anna, a 36-year-old web designer living in south Moscow, told AFP the lockdown would be hard for her and her five-year-old daughter, but promised to "observe the quarantine" as she walked to the shop to buy bread.
But some were in no hurry to take the new rules to heart. Three teenagers flouted social distancing rules, walking and laughing together.
"Staying home with our parents will kill us quicker than the coronavirus," said one teen as the others nodded.
-- Regions eye lockdowns --
At least 14 regions on Monday followed Moscow's lead and introduced strict measures, including Russia's second city Saint-Petersburg with a 5.4 million population.
Some parts of the country ordered even more draconian restrictions.
Chechnya's strongman Ramzan Kadyrov ordered a halt to all traffic in and out of the region, while masked men in black uniforms were patrolling the streets according to a video published by independent Novaya Gazeta newspaper.
In a televised conference with his regional representatives, Putin ordered an inventory of hospital beds and ventilators and threatened consequences if the national measures are not enforced.
"It's not lack of discipline and common sense, it is criminal negligence," he said of local authorities who neglect to close down entertainment venues.
Putin also took a call from US President Donald Trump with the two leaders discussing cooperation on the coronavirus response, the Kremlin said, without giving specific details.
Over the past 24 hours Russia recorded 302 new coronavirus cases -- the biggest daily increase so far -- taking the national tally to 1,835 cases of coronavirus and nine deaths.
At a government meeting, Prime Minister Mikhail Mishustin said a Moscow-style lockdown across the country was important to pre-empt a major outbreak.
He ordered the unlocking of 33.4 billion rubles ($418 million) to help 77 Russian regions with additional hospital beds and medical equipment.
In a rare televised address last Wednesday, Putin announced that Russians would not be required to go to work this week, but would still get paid. He also postponed a key public vote on constitutional reforms that would allow him to stay in power until 2036.
The government has yet to announce any significant measures to help the economy, and Russia's central bank on Monday warned that containment measures will lead to "a temporary but significant drop in economic activity in the coming months".
- 'Pray at home' -
The powerful Russian Orthodox Church, which had initially said authorities had no right to close churches, finally fell into line on Sunday, with Patriarch Kirill calling on the faithful to pray at home.
"You can be saved without going to church," he told believers in an address.
The new isolation rules, which will be policed by a vast system of facial-recognition cameras in Moscow, came into force as Russia also closed its borders.
