The cause of the fire is not yet clear. Among the dead is a young girl who lived near the storage, the fire service said. The fire is under control. More victims are being sought.
The fire raged in a poor neighborhood in eastern Lima. An area of about 500 square meters was affected.
Fires regularly occur in the suburbs of the Peruvian capital, which is home to many old buildings that store combustible materials. Often they do not meet the safety standards.
