A two-storey building has collapsed in the Bode area of Ibadan, the Oyo state capital, leaving many of its occupants trapped in the rubble.
The incident reportedly occurred before dusk Friday, and concerned residents quickly trooped to the scene, making efforts to rescue victims before the arrival of government officials.
Men of the fire service who arrived the scene were said to be helpless as they have no equipment to rescue victims.
It is understood that some of the victims called friends and relatives via telephone.
The incident comes exactly 48 hours after a three-storey building collapsed in the Ita-Faaji area of Lagos Island, killing at least 12 persons, including nine children, and injuring almost 50.
It is not yet certain what led to the collapse of the structure in Ibadan.
