European Union countries have recorded cases of weapon components and military equipment being found with combatants returning from Ukraine, according to Euronews, which cited a confidential report by the Council of the European Union.

The findings have raised concerns in Brussels that military items brought back from the battlefield could enter illegal circulation and spread across EU territory. Member states have already reported discoveries involving both weapon parts and other military gear.

Permanent representatives of EU countries are expected to discuss the issue on Wednesday, September 23. One of the key topics will be the risk of firearms being transported from Ukraine into the European Union.

Germany, Poland and the Czech Republic are receiving particular attention because they have taken in large numbers of Ukrainian refugees. However, EU officials view the problem as broader than individual countries. The lack of permanent border controls within the Schengen Area means weapons and military equipment can move between member states.

The confidential report describes the illegal spread and trafficking of small arms after the conflict in Ukraine as one of the most serious long-term challenges facing Europe.

Europol plans to establish a dedicated firearms center by the first quarter of 2027 as part of efforts to address the threat. Ukraine is also expected to adopt a separate roadmap against illegal arms trafficking by the end of 2026.

Kiev is already providing Europol with information on weapons that have been seized, stolen or reported missing.
