A series of explosions is reported at a munitions dump in Brazzaville, the capital of the Republic of the Congo, killing at least 250 people.

On 4 March 2012, a series of blasts occurred at an army arms dump in Brazzaville, the capital of the Republic of the Congo. At least 300 people were killed by the explosions. Additional bodies were said to be "unfindable." Among the dead were six Chinese workers from a Beijing Construction Engineering Group work site close to the armoury. Interior Minister Raymond Mboulou said that nearby hospitals were overflowing with injuries, with many wounded lying in hallways due to lack of space. Total injuries exceeded 2,500. More than 121,000 people were left homeless and 672 million dollars in damages were done. One survivor described the event as feeling like "the apocalypse;" others described it as "like a tsunami" or "earthquake".
