Motor Rifle Brigade from Kemerovo Oblast surrendered to Ukraine, saying they "didn't know that they were brought to Ukraine to kill Ukrainians". Ukraine held a series of press conferences with about a dozen POW's, where the POW's made comments against the invasion, how they had been manipulated and for the conflict to end. While some have raised concerns that the conferences breach the Geneva Convention through potential unnecessary humiliation, US journalists who spoke to POW's independently of the conference claimed there was no intervention by Ukraine officials, by physical or mental coercion. According to The Guardian, while it was likely that Ukraine was using the discomfort of captured soldiers for propaganda purposes, still the videos succeeded in showing the Russian servicemen's "authentic sense" of regret for having come to Ukraine. Amnesty International argued that Article 13 of the Third Geneva Convention prohibits videos of captured soldiers. Captured Ukrainian soldiers with British citizenship were recorded calling for Boris Johnson to arrange for them to be freed in exchange for pro-Kremlin Ukrainian politician Viktor Medvedchuck. The videos were broadcast separately on Rossiya 24 TV channel, causing MP Robert Jenrick, to call the videos a "flagrant breach" of the Geneva Convention. A Russian spokeswoman claimed that she had also told Johnson during a phone call about the men's treatment that the UK should "show mercy" to the Ukrainian citizens by stopping military aid to the Ukrainian government when asked to show the men mercy. On 11 March it was stated by the Ukrainian Defense Ministry that Russian armed forces were attempting to coerce Ukrainian POW's to fight for Russia in exchange for amnesty. The head of the Ukrainian Coordination Headquarters for POW Treatment, Iryna Vereshchuk, raised concerns that Russia had not released information to Ukrainian authorities on the location of any Ukrainian POW's and the International Red Cross had not been allowed to see them, as of 16 March. By 21 April, Russia claimed that 1,478 Ukrainian troops had been captured during the course of the siege of Mariupol. On 22 April, Yuri Sirovatko, Minister of Justice of the Donetsk People's Republic, claimed that some 3,000 Ukrainian prisoners of war were held in the territory of the DPR. On 20 May, the Russian Ministry of Defense claimed that 2,439 Ukrainian soldiers had been taken prisoner over the previous five days as a result of the surrender of the last defenders of Mariupol, entrenched
