WATCH: Ukrainian authorities have released footage of searches targeting participants in the Nov. 2 unrest outside a National Guard facility near Kyiv, where protesters gathered amid allegations that AWOL service members were illegally held and mistreated. The SBU says it has identified about 100 people who actively participated in the unrest and is considering further arrests and charges. Searches were carried out in the homes of some of the participants. Ukrainian officials deny that the building was a "torture chamber," while the military ombudsman and investigators are looking into allegations of abuse. The claims that a 14-year-old boy was kept inside have not been proven; Available footage suggests he was among the protesters.
