An official in Republic of Congo says four high-ranking officers have been arrested after a series of blasts at an arms depot left at least 292 people dead.
Justice Minister Emmanuel Aime Yoka announced late Tuesday that the four were under investigation following last month's blasts. More than 2,000 others were injured.
Among those under investigation is Col. Marcel Tsourou, who serves on the country's national security council.
The justice minister said Tsourou's two lawyers also had been taken in for questioning after they tried to hold a press conference.
The cause of the fire that set off the detonation has been blamed on a short circuit, but residents claim witnesses saw a soldier throw a cigarette inside the armory.
