The African Union (AU) is warning that attacks in major cities far from active front lines can rapidly escalate the conflict in the Democratic Republic of Congo (DRC), raising civilian casualties and widening regional instability especially when critical infrastructure is targeted.

A city strike changes the risk equation

In its February 6 statement following the reported drone attack on Kisangani’s Bangboka airport, the AU Commission argued that extending hostilities to urban centers “far from the front lines” increases the likelihood of escalation and creates unacceptable risks for national and regional stability. Kisangani, capital of Tshopo province, is a major transport and administrative hub meaning any security shock there has ripple effects well beyond the immediate incident.

Airports are not just transit points. In conflict settings, they can be linked to humanitarian access, medical evacuations, cargo routes, and the movement of officials and security services. That is why the AU framed the Kisangani incident as an act that “seriously endangers civilian populations” and warned it may violate international humanitarian law principles specifically distinction, proportionality, and precaution.

The AU’s core concern: escalation and spillover

The AU’s warning reflects a broader fear: once violence moves beyond the primary conflict zones, it becomes harder to contain.

Urban expansion of attacks can:

• Increase civilian exposure in densely populated areas;

• Trigger displacement and deepen an already critical humanitarian situation in eastern DRC;
