Internal fighting in Ethiopia and a drone strike on Khartoum airport have escalated security tensions along the Ethiopia-Sudan border.
The escalation threatens to draw Sudan into a broader regional conflict while placing thousands of Sudanese refugees in Ethiopia at significant risk.
On Monday, May 6, 2026, a drone attack targeted Khartoum International Airport [1]. Sudanese officials, led by General Abdel Fattah al-Burhan, said Ethiopia was involved in the strike [1]. However, authorities in Addis Ababa said they had no involvement in the attack [2].
These diplomatic frictions coincide with intensifying internal clashes within Ethiopia. Government forces and allied militias, including Tigray forces, have been fighting in the Amhara region for more than one year [3]. The conflict has been particularly severe in the north-west Amhara region, where the spill-over of war has destabilized the frontier.
Security experts said the instability is fueled by the ongoing struggle between the Ethiopian army and Tigray-aligned militias. This internal volatility has created a precarious environment for Sudanese refugees residing in Ethiopia, who now face increased vulnerability as the fighting nears the border [3].
Tensions between the two nations have been escalating throughout 2025 and 2026 [2]. The combination of territorial disputes and the recent drone incident has pushed the relationship toward a critical point, with both nations increasing their military readiness in the border areas [2].
“Sudan accuses Ethiopia of involvement in the drone strike on Khartoum airport.”
The intersection of Ethiopia's internal instability and the diplomatic rift with Sudan creates a volatile security vacuum. When domestic conflicts—such as the war in the Amhara region—spill over into international borders, it often transforms local grievances into geopolitical crises. The dispute over the May 6 drone strike suggests a shift from passive tension to active hostility, which could jeopardize humanitarian corridors for refugees and trigger a multi-state military escalation in East Africa.
