Update (1451ET): Interfax is reporting that a Russian watchdog says Twitter is now blocked in Russia, adding to the western social media freeze that now includes Facebook and access to app stores.

Update (1437ET): Vladimir Putin signed several laws on Friday - including one which would seize the assets of foreigners if they harm Russians or otherwise infringe on Russian rights, according to Interfax.

The threat comes in parallel with another law signed on Friday which will criminalize whatever the Kremlin deems "disinformation" about the military in a crackdown on "fake information." As a result, the BBC has pulled all reporters from Moscow.

Meanwhile, Moscow has offered foreign companies three options for a path forward: remain in Russia, exit entirely, or hand over their holdings to local managers.
