One explosion happened outside a gas station, while the other was near the Bakassi camp for internally displaced persons (IDP), underscoring the continued threat from Boko Haram terrorists who are suspected of being behind the attacks.
"Two suicide bombers riding in motorised rickshaws this morning detonated their explosives 10 minutes apart, with one of them targeting the Bakassi IDP camp on the outskirts of the city," Mohammed Kanar, spokesman for Nigeria Emergency Management Agency (NEMA), said.
"One of the bombers tried to enter the Bakassi IDP camp but the explosives detonated at the gates, killing four people," Kanar said.
"The explosives on the other one detonated minutes later as he rode with two other people towards the (Bakassi) IDP camp near the fuel depot."
Following the blast, one of the yellow rickshaws burst apart in half, while the ground was littered with metal shards.
"Nine persons lost their lives with twenty-four persons injured and evacuated to various hospitals," NEMA said in a statement posted on Twitter.
