The Scottish Courts and Tribunals Service (SCTS) confirmed that an appeal against the sentences had been lodged. Belov's solicitor, Larry Flynn, told BBC Scotland News the appeal would focus on his client's addition to the sex offenders register rather than the supervision or unpaid work order.
The case stems from an incident in the Lochee area of Dundee in which the two girls were assaulted. The trial heard that Belov said "hello sexy, I'll show you a good time" to the girls as he walked past them. After one of the girls called him a creep, he returned to confront the group and called his sister, who arrived shortly afterwards and assaulted one of the girls.
Belov claimed he had seen the girl's weapon and, fearing for his sister, pushed her. He also claimed the children had called him a migrant and used an expletive. Sheriff Niven-Smith rejected Belov's claim of self-defence and said the girls' evidence had been "eloquent."
The attack drew international attention after a video of one of the child victims holding an axe and knife circulated widely. Elon Musk highlighted the footage and criticised her arrest for "trying to defend herself."
Belov was convicted in June of assaulting a 12-year-old girl and uttering sexual remarks to the girl and her friends, and the siblings were sentenced earlier this month.
