Protesters rally outside the US embassy in Kyiv to bring attention to the fate of Ukrainian prisoners of war and ensure their inclusion in any deal to stop the conflict with Russia. Kateryna Buhutska is one of around 200 people at the protest, holding a picture of her son before he was taken prisoner in the southern Ukrainian city of Mariupol. "I don't understand what is happening in the world. We are scared of everything that is said in the news, but we are here to remind you that our boys, fathers, sons, husbands, must be returned," she says. The UN has warned of widespread and systematic torture in Russian prisons, with 95 percent of released Ukrainian POWs providing accounts of torture or ill-treatment. IMAGES AND SOUNDBITES
