Three Ethiopian militants were killed and an unspecified number injured following a gun duel between Ethiopia-backed militants and Sudanese troops.
Two others were captured in the clash that happened along the Sudan/Ethiopia border on Tuesday.
“A Sudanese reconnaissance platoon was attacked by an Ethiopian force near the border, leading to the death of three, two taken as prisoners from the Ethiopian side, in addition to a number of injured,” a source said.
The border conflict between the two Nile valley countries escalated in November 2020, with Sudanese troops advancing into the contested Al-Fashaga triangle.
The triangle is a 600 square kilometer (150,000 acres) stretch of fertile agricultural land seized by Ethiopia in 1995 following a spat between Sudan and its two Nile valley neighbors.
The conflict was further complicated by the settlement of thousands of Ethiopian farmers in the disputed area, provoking calls for full withdrawal and a return to the pre-November status-quo by the Ethiopian side.
The Ethiopian Foreign Ministry earlier called on both sides to reach an amicable solution through negotiations.
