A court in southern Russia convicted 15 captured Ukrainian soldiers on terrorism charges Friday after a trial that Kyiv denounced as a sham and a violation of international law. The military court in Rostov-on-Don sentenced 15 men from the Aidar battalion, which Russia has designated a terrorist group, to prison terms ranging from 15 to 21 years.

The verdict marks the second mass trial of Ukrainian prisoners of war since March, when 23 members of the elite Azov brigade were convicted on similar charges in a trial that also was condemned by Ukraine as a violation of international law.
