The BBC has seen direct evidence of civilian kilings by Russian forces, but in Russia, it's a crime to report news of these attacks and bombardments, and illegal to even call the invasion of Ukraine by Russia, a war. Anyone who contradicts the official line on Russian military action risks arrest and up to 15 years in prison. Dozens of people have already been prosecuted for protesting or writing about the war - the latest in a long line of moves by President Putin to stifle free speech and eliminate checks on his power.
However, some Russian journalists are defying the censorship. The BBC's Europe correspondent Sarah Rainsford speaks to some of those who are determined to report the facts from Ukraine.
"Truth is the regime's main enemy and it's using this law to squash all dissent in Russia and scare people into silence."
