Ukraine invasion: Russia restricts social media access

Russia has blocked Twitter and threatened to do the same with Facebook after a clash over "censorship".

Russia's communications regulator Roskomnadzor accused Facebook of violating "the rights and freedoms of Russian citizens".

Facebook said it had refused to stop fact-checking and labelling content from state-owned news organisations.

Internet connectivity watchers at NetBlocks say there is a total or near-total restriction on Twitter in Russia.
