Sumy residents attend an emergency first aid demonstration held by volunteers from Ukraine’s Hospitaliers on a Saturday morning 18 August. The demonstration is held barely five hours after a strike in one of the city’s neighbourhoods. Hosting the demonstration is volunteer Artem Selianin, who patiently assists the attendees and explains the basics. He says: "If you do not have any knowledge, you do not know what to do. If you have some knowledge, you will do something." IMAGES AND SOUNDBITES
