In Dnipro, teachers prepare Molotov cocktails while volunteers coordinate a huge aid stockpile.
On the day Vladimir Putin ordered his soldiers into Ukraine, Arina had planned a dance class after work and then a party. Three days later, the English teacher was making Molotov cocktails in a park.
"It's pretty terrifying. I think we don't really realise what it is we're doing; we just need to be doing something," she said. The steps of a nearby hall are heaped with donated clothes, blankets and buckwheat. A stream of people keep arriving with more - including petrol, water and toiletries - as volunteers yell instructions on where to take it all.
There's a whole separate area for those who want to get a weapon and sign up to fight; that queue stretches far off into the distance. "We're at a peak, I think. There's fighting on all sides of us," hospital spokesman Sergei Bachinsky told me, his voice quietly urgent.
