There were no injuries or deaths reported, investigators said. The blaze reached Task Force Bravo.
Initial reports showed that the fire started at about 12:45 p.m. at a squatters area in Kasiyahan street, Don Antonio Heights in Barangay Holy Spirit. Authorities have yet to determine the cause of the blaze.
Panic-stricken residents carried what they could of their meager belongings and could only watch from a distance as their houses burned.
They were immediately evacuated to safety. A barangay hall was set up as temporary shelter for affected families. The Quezon City government is expected to provide relief goods, firefighters said. Matthew Estabillo
