Ukraine invasion: Russia passes law threatening 15 years in jail for spreading 'fake' information about the military
People who spread "fake" information about Russia's armed forces could be jailed for up to 15 years after the country's parliament approved a new law.
It also makes public calls for sanctions against Russia a criminal offence.
"If the fakes lead to serious consequences then imprisonment of up to 15 years threatens," said the lower house of parliament, the Duma.

The new law appears designed to give Russia even stronger powers to supress information about its invasion of Ukraine, which the Russians call a special military operation.
It now heads to Russia's upper house of parliament, where its sign-off is a formality, with Duma speaker Vyacheslav Volodin saying it could come into force on Saturday.
People spreading so-called false information could get up to three years in prison - or as many as 15 if it has "severe consequences".
Russian news outlets have been ordered to only publish information from government sources and must describe the situation in Ukraine as a "special military operation" - "war" and "invasion" are banned by media regulator Roskomnadzor.

Western sources such as the BBC, Deutsche Welle, Radio Free Europe and others are also now being blocked by the regulator for spreading "fake" information, Russia's Interfax news agency said on Friday.
Some independent Russian media have already had to close or suspended service after going against the government line, including radio station Ekho Moskvy and TV station Dozdh.
The editor of Dozdh has fled Russia and told Sky News the situation had been getting "worse and worse" over the last few days and that he and colleagues had been threatened.

And - just two hours after the law was passed - news website Znak said it was closing due to "the large number of restrictions which have appeared recently affecting the work of media in Russia".
International technology and social media giants are also at the heart of the information battle.

Twitter and Facebook have both reported having their services restricted and deliberately slowed down for clamping down on media sources linked to the Russian state.
Facebook policy chief Nick Clegg said it had refused Russia orders to stop fact-checking and labelling content from state-owned media companies.
The Reporters Without Borders group has said "the information war is in full swing in Russia" and that President Vladimir Putin needed all national media on a "battle footing in order to justify the invasion of Ukraine".
Despite censorship efforts, it's extremely hard to block the huge flow of information via social media and the internet.
Protests have been held in many Russian cities but most are quickly broken up, with police often hauling people away into vans.
