'There is an eruption of anger' within Russia towards President Vladimir Putin's military moblisation order - reports ITV News correspondent Sejal Karia.
Russian police moved quickly on Saturday to disperse peaceful protests against President Vladimir Putin's military mobilisation order, arresting hundreds, including some children, in several cities across the country.
More than 700 people were detained by police, including over 300 in Moscow and around 150 in St Petersburg, according to OVD-Info - an independent website which monitors political arrests in Russia.
According to its analysis some of the arrested individuals were minors.
The demonstrations mirrored protests which followed immediately after the Russian president signed a decree, last Wednesday, ordering the conscription of some 300,000 reservists.
Russia's Defense Ministry has said IT workers, bankers and journalists will be exempt from being called up to fight on this occasion, but it has not ruled out further troop mobilisations in the future.
Most Russian men aged between 18 and 65 are automatically counted as reservists.
On Saturday, police deployed in force throughout cities where protests were scheduled by opposition group Vesna and supporters of jailed opposition leader, Alexei Navalny.
They moved quickly to arrest demonstrators, most of them young people, before any protests could be held.
