Thirty people were killed and 67 injured in the suicide blasts which rocked a crowded market in Madagali district of Nigeria's northeastern state of Adamawa on Friday.

Badare Akintoye, a military spokesman confirmed two female suicide bombers carried out the attacks.

The explosions occurred simultaneously at the opposite ends of the local market in Madagali, causing buyers and sellers to run for safety.

In a statement sent to Xinhua, Sani Datti, spokesman of the country's National Emergency Management Agency said the 67 injured were taken to the state-run Michika General Hospital for treatment.

The market at which the attacks took place is a weekly one that sells grains, vegetable and animals every Friday.

The blasts occurred at the animal and grains sections of the market, according to Yusuf Mohammed, a senior district official.

Adamawa State police spokesman Othman Abubakar said investigation is underway on the attacks.

Madagali is located 276 kilometers from the state capital, Yola.

In August 2014, the district was one of several towns seized by terror group Boko Haram but it was recaptured by the military in March 2015.

Two female suicide bombers who were members of the Boko Haram group killed at least 30 people and 16 injured when they attacked a busy motor park in Madagali on Dec. 28, 2015.

Madagali is a neighboring district to Borno State, where Sambisa, the largest training camp of the ruthless Boko Haram group is situated.

The northeast region of Nigeria has been a stronghold of the extremist group and has been frequently raided in the past six years.

In past months, the Nigerian government has launched several military operations to eliminate the terrorist threat.
