Sudan's army said Saturday several soldiers had been killed in an attack by armed groups and militias linked to the Ethiopian military in a disputed fertile border region.
Relations between Khartoum and Addis Ababa have soured over Al-Fashaqa, a border zone long cultivated by Ethiopian farmers but claimed by Sudan.
"Our forces tasked with securing the harvest in Al-Fashaqa … were attacked by groups of Ethiopian army forces and militias, who sought to intimidate farmers and spoil the harvest season," Sudan's armed forces said in a statement.
Sudanese troops "repelled the attack" and "inflicted heavy losses in lives and equipment" on the Ethiopian side, it said.
But the attack left "several killed" among Sudanese forces, the army added.
Ethiopian officials could not be immediately reached for comment.
Al-Fashaqa, which also borders Ethiopia's troubled Tigray region, has seen sporadic deadly clashes between the two sides over the years, but escalated last year.
Tensions rose after fighting erupted in Tigray in November 2020, which sent tens of thousands of refugees fleeing into Sudan.
Khartoum and Addis Ababa have since been locked in a tense war of words over the region, trading accusations of violence and territorial violations.
The border dispute feeds into wider tensions in the region, including over Ethiopia's controversial Blue Nile dam.
Sudan, along with Egypt, has been locked in a bitter dispute over Ethiopia's mega-dam for a decade.
Both downstream countries, dependent on the river for most of their water, see the Grand Ethiopian Renaissance Dam as an existential threat.
