More than 100 people have been arrested by Russian authorities at spontaneous memorials for Alexei Navalny, a rights group said this morning.

People were seen gathering to place flowers at makeshift monuments across Russia late Friday, and in some cases were detained by police, social media footage showed.

As of this morning, “more than 101 people” had already been detained in 10 cities, including 64 in Russia’s second-largest city of Saint Petersburg, OVD-Info said.

Eleven people were detained in Moscow, and multiple others in the cities of Nizhny Novgorod, Krasnodar, Rostov-on-Don and Tver, it said.

Authorities in Moscow said yesterday that they were aware of calls online “to take part in a mass rally in the centre of Moscow” and warned people against attending.

Putin’s long-standing opponent, Navalny died after he fell ill on a walk at the Arctic penal colony where he was being held, Kremlin authorities claimed. The UK Government said last night that it had “summoned the Russian embassy” to make clear that it holds the Russian authorities “fully responsible”.
