Sudan's army accused Ethiopian troops on Tuesday of attacking a military camp in northern Sudan and killing about 19 people.
Ethiopian officials were not immediately able to comment on the attack which Sudan's army spokesman said happened early on Monday in the Jabel Hantub area of Sennar state.
"They hit a camp belonging to the central reserve police and they killed about 19 people," the army spokesman said. He did not know how many people were injured.
The central reserve police are a heavily armed military unit and are often deployed along border areas or to defend the capital Khartoum.
"This was an attack and we don't know the reason -- we have no problem with Ethiopia and there are no border disputes or tribal clashes in that area," the army spokesman said.
Sudan signed a north-south peace deal in 2005 which ended Africa's longest civil war and also improved relations with its east African neighbours.
One Sudanese security source and another government official said the attack may have been because Sudan had given refuge a few weeks earlier to local Ethiopian officials and refused to hand them over to Addis Ababa.
It was not clear why they had sought refuge in Sudan. Ethiopia is fighting fighters from the Oromo region which borders Sudan and who want greater autonomy for their areas.
The Sudan army spokesman said a joint Ethiopian-Sudanese committee had been formed to investigate the attack.
