The Eritrean–Ethiopian border conflict refers to an ongoing violent standoff of Eritrea and Ethiopia as part of the violence in the Horn of Africa, including sporadic clashes of their militaries in line with the Second Afar Insurgency. The border conflict has been ongoing since the Eritrean–Ethiopian War of 1998-2000, and has included multiple clashes with numerous casualties, such as the 2016 Tserona clashes.
Eritrea achieved independence from Ethiopia in 1993, following a long armed struggle. The two countries fought again in 1998-2000 over the disputed territory of Badme, with an estimated 70,000 to 80,000 dead.
In 2012, Ethiopia launched an offensive into Eritrean-held territory, with a number of people killed and others captured when three camps were attacked according to a defense official said. Several weeks prior to the offensive Ethiopia blamed Eritrea for supporting the Ethiopian rebels, who staged a January 2012 raid in the northern Afar region that killed five Western tourists.
On June 2016, Eritrea claimed 200 Ethiopian soldiers were killed and 300 wounded in a battle at Tsorona.
