Nearly 30 people were killed and more than 80 others were wounded in a series of suicide bombings near Maiduguri, the capital of Boko Haram-infested Borno state in Nigeria on Tuesday (15 August).

Three female suicide bombers detonated themselves in a busy marketplace in Konduga village and a refugee camp in the town of Mandarari in Borno, CNN quoted civilians as saying.

Local media also reported fresh attacks and casualties in some villages in Amarwa along Maiduguri-Konduga Road in Borno state. The government or the Nigerian army was yet to issue a statement on the attacks and reveal the official casualty figure. The reported death toll is expected to rise as rescue work continues at the attack sites.

"The first bomber struck outside the IDP [internally displaced persons] camp overlooking the market at around 6pm local time [1pm ET] hitting some people and causing confusion as people tried to flee," civilian vigilante Bukar Kyari told CNN.

While traders were trying to close their shops and evacuate their wares, two female bombers hit the market "almost simultaneously," said another civilian vigilante, Usman Grema.

The attack on the market had a bigger impact as it was a weekly market day when people from the town and nearby villages rush to the market to buy and sell food, clothing and livestock, CNN wrote.

The news channel quoted a medic from a hospital in Maiduguri as saying that 28 people were killed at the explosion site, while two others died after being taken to a hospital.

No group has so far claimed responsibility for the attack, but the Konduga district is known for Boko Haram insurgency.
