Russian police have reportedly arrested hundreds of protesters rallying against the Kremlin’s decision to call up thousands of extra troops to join the war in Ukraine. Russian human rights group OVD-Info put the total detained at more than 1,000, most of whom were arrested in St. Petersburg and Moscow. Dozens were held in several other cities. Flights out of Russia sold out fast after Vladimir Putin’s announcement of a partial mobilisation of troops. The partial mobilisation means some 300,000 military reservists will be drafted to bolster Russia‘s forces who have suffered recent battlefield setbacks in Ukraine. The move came a day after occupied areas of Ukraine announced snap referendums on joining Russia. In remarks condemned by Ukraine and its allies, Mr. Putin stressed that he would use “all available means” to protect Russian territory – implying this could involve nuclear weapons.
