Dozens of supporters gather in sub-zero temperatures in front of the Russian Supreme Court in central Moscow as judges reconvene to hear a request to shut down Memorial, the country's most prominent rights group and a pillar of its civil society. In court for alleged violations of its designation as a "foreign agent", Memorial is facing its biggest threat since it was founded by Soviet dissidents, including Nobel Peace Prize laureate Andrei Sakharov, in 1989. Prosecutors have asked the Supreme Court to dissolve Memorial International, the group's central structure, for alleged failures to use the "foreign agent" label on all their publications, including social media posts, as required by law.
