The 78-year-old Ukrainian grandmother preparing for a Russian invasion

As fears of a Russian invasion of Ukraine grow, some Ukrainian civilians in Mariupol have taken up basic weapon training to defend themselves.

They included 78-year-old grandmother Valentina Konstantinovska who told the BBC that "when an invader comes, I will resist and I will be furious."

The trainers in Mariupol were the Azov brigade - a far-right group with a controversial history, now officially part of the National Guard.

Other branches of the Ukrainian military are providing the same kind of training in locations across the country.

Russia has denied any plans to invade Ukraine, despite 100,000 soldiers gathering on Ukraine's borders.
