An explosion partially destroyed an Algerian paramilitary police barracks and killed at least four people, including two police officers, a security source said on Friday.
"We have at least four people killed and among them two gendarmes (paramilitary police)," said the security source, who did not want to be identified.
Two local people said they heard an explosion at about 3 a.m. (0200 GMT) on Friday at the barracks, which is next to a major highway in the village of Ammal, about 60 km (40 miles) east of the capital Algiers.
There was no official confirmation that there had been an attack and an officer at the barracks refused to comment on what happened.
A Reuters reporter at the scene said the front perimeter wall of the barracks had been completely destroyed and that some of the buildings inside the perimeter had also been wrecked.
The base housed a unit of the gendarmerie, or paramilitary police, who have responsibility for law and order in rural areas of Algeria.
