ABUJA, July 1 (Xinhua) -- At least 10 people were killed on Tuesday after an explosion rocked an international market in the heart of Maiduguri, capital of northeastern Nigeria's Borno state, witnesses, hospital and security sources said.
Besides, two bodies of the bombers were recovered from the scene of the blast which occurred at about 8:10 a.m. local time (0710 GMT) at the entrance of the Monday Market, said a source at the Maiduguri Specialists Hospital.
The source said more than 15 injured people were brought to the hospital on Tuesday morning.
A security source said rescue operation was still ongoing at the scene of the bomb blast.
A Xinhua reporter in the state said the bomb exploded at the busy market near the Power Holding Company of Nigeria (PHCN) building, a crowded commercial area.
He said the bombing would be the first major attack by the Islamist sect Boko Haram since the beginning of Muslims fasting period, the Ramadan.
The bombing came barely 24 hours after Nigerian troops said a terrorists' intelligence cell headed by a businessman has been busted. The man participated actively in the abduction of school girls in Chibok.
Spokesperson for the Nigerian Defense Headquarters Chris Olukolade said in a statement that the man, Babuji Ya'ari, who is also a member of the Youth Vigilante Group, spearheaded the murder of the Emir of Gwoza.
Olukolade said the suspect's main role in the group is to spy and gather information.
President Goodluck Jonathan on Monday said the country will leave no stone unturned to reinforce its defense against terrorism.
