A series of fiery blasts killed 20 people and injured dozens more at a military camp in Tanzania, authorities said early Thursday. At least 184 others were wounded in the blasts at an army base in the main city of Dar es Salaam, said Nyancheghe Nanai, assistant director of disaster management. Several arms and ammunition depots at the Gongola Mboto army base were destroyed, authorities said. Residents panicked as the chain of explosions overnight Wednesday sent orange plumes into the sky. The explosions rattled neighborhoods, leveled nearby homes and forced the closure of the main international airport. An evacuation center for the displaced has been set up at a nearby stadium, according to Nanai.
