The blaze was caused by an unattended iron which overheated.
Fire Officer 4 Jose Nagpacan said the fire broke out at around 5:40 p.m. on the second floor of a house on Makabayan street, Barangay Obrero, Tomas Morato.
The fire immediately spread to neighboring houses, which were mostly made of light construction materials .
Responding firemen had difficulty putting out the blaze because firetrucks could not enter the narrow streets in the area.
A fire-out was declared at around 8:40 p.m.
Allan Dipos, 23, sustained a cut in the foot after he stepped on a protruding galvanized sheet while trying to save appliances from his house.
All families affected by the fire were evacuated to the Barangay Obrero plaza.
