A Sudanese patrol came under shelling from Ethiopian forces on Sunday near the border with Ethiopia, according to local media.
No injuries were reported and the Sudanese military has yet to issue an official statement.
Sudan Tribune news portal, citing a military source, said mortar shells were fired by Ethiopian forces at the patrol in the eastern Al-Gadaref province.
Last week, Sudan’s Prime Minister Abdullah Hamdok informed UN Secretary-General Antonio Guterres that Sudanese forces were deployed within the country’s borders. Hamdok stressed that Khartoum was not seeking war with Addis Ababa.
The attack came amid rising tensions between Khartoum and Addis Ababa over their borderline.
Sudan accuses Ethiopia of supporting militias that attack Sudanese army forces in the border area, an accusation denied by Addis Ababa.
