Colombian sentenced to 28 years in Russia for fighting in Ukraine

In addition to “mercenaryism,” he was also charged with “illegal border crossing” and “weapons and ammunition smuggling.” The ruling highlights Russia's rigorous prosecution of foreigners fighting for Ukraine because they do not enjoy the protection of prisoners of war under the Geneva Conventions.
In the summer of 2024, the Ukrainian army invaded the Russian border region of Kursk and occupied around 1,400 square kilometers. However, the last Ukrainian units had to withdraw from this region in April 2025, further complicating the security situation.
Legal situation for mercenaries
The situation of mercenaries in international law is ambiguous. How taz reported, mercenaries are considered people who are not incorporated into state armed forces and who take part in armed conflicts for commercial reasons.

In many conflict regions, national law enforcement authorities suffer from weak state structures, which makes it difficult to prosecute mercenaries. In addition, in the past, intergovernmental agreements have often provided additional protection for employees of private security companies.

The conviction of Pablo Puentes Borges and the background to the mercenary deployment illustrate the delicate legal and ethical questions in times of armed conflict.
