A few prisoners got hold of guns belonging to the wardens.
Three people died and four suffered bullet injuries Thursday during a short-lived mutiny at a jail in Congo's capital Brazzaville, the prosecutor said.
The unrest broke out in the afternoon at a prison near the city's court when a few prisoners got hold of guns belonging to the wardens, Andre Ngakala Oko said.
"They started shooting in all directions creating panic," he said, adding that the three dead included a "gendarme, a mutineer and a civilian killed by a fleeing mutineer.
"Four people were wounded: three mutineers and a civilian," he said.
Witnesses said the short-lived riot lasted around 30 minutes. The prosecutor said all the prisoners who had tried to flee had been apprehended and locked up in their cells.
