Eritrean–Ethiopian War
The fighting quickly increased to using artillery and tanks. On 5 June 1998, the Ethiopians launched air attacks on the airport in Asmara and the Eritreans retaliated by attacking the airport of Mekele. These raids caused civilian casualties and deaths on both sides of the border. The United Nations Security Council adopted Resolution 1177 condemning the use of force and welcomed statements from both sides to end the air strikes.
