“It’s dangerous here. It is difficult, mentally and physically. We are all tired, but we are coping,” says Yuriy, the commander of all the brigade's medical units.

The brigade warned e-bike users to check their batteries after battery packs were officially classed as "dangerous" products by the UK's regulatory body.
