This is the best summary I could come up with:

After living over a year under Russian control in the southern Ukrainian town of Novaya Kakhovka, Primak, a former shopkeeper, decided in June 2023 that she could no longer bear foreign occupation.

The volunteers, often ordinary anti-war Russians looking for ways to express how they feel about the conflict, operate largely through word of mouth and groups on the Telegram messaging app.

Demidenko died last Friday in pre-detention custody in Belgorod where he had spent six months awaiting trial on charges of illegal gun possession, which his family and friends say were politically motivated as retribution for his volunteer efforts.

People who knew Demidenko, fellow volunteers and Ukrainian refugees whom he has aided, portray him as a man of unwavering commitment to helping those in distress, despite the risks faced in wartime Russia.

To make ends meet from a meagre salary, Demidenko sold foreign language textbooks on the side, a job through which he met his wife, Natalia Vishnevskaya, in 2014.

On social media, he rallied against taxi drivers who charged big sums to drive refugees to the border, while also claiming that officials had been demanding money for fast-tracking people through the queues.
