A residential fire that broke out in a densely populated area known as “Maisan” at the corner of Cabildo and Anda Streets in Intramuros, Manila, remains on fourth alarm, affecting at least 300 houses and around 600 families as of the latest reports.

The fire started on Wednesday afternoon, Feb. 25, at around 5 p.m., quickly sending large plumes of smoke into the sky, which alerted residents and employees of nearby commercial establishments.

The Bureau of Fire Protection (BFP) said the fire was initially raised to a second alarm at 5:08 p.m., prompting the dispatch of additional firefighting units. As the blaze intensified, it was further elevated to fourth alarm at 5:28 p.m.

Firefighters continued to arrive and conduct suppression operations to prevent the fire from spreading to nearby structures in the densely populated community.

Electricity in several streets was temporarily cut off to minimize hazards and allow fire trucks to operate safely.

According to residents, the fire may have been deliberately set. Witnesses alleged that a man, recently released from New Bilibid Prison, poured gasoline into one of the houses before the blaze started.

Barangay 655 Chairman Johny Yacub confirmed that the man has already been detained by the Manila Police District (MPD) for investigation.

Many residents in the area work as stall owners and vendors at nearby talipapas, while others are workers and students, including those attending Manila High School, which is also located in Intramuros. Residents hurriedly evacuated with only essential belongings, leaving behind homes and personal items.

Authorities advised motorists and the public to avoid Victoria, Magallanes, and Cabildo streets to allow emergency vehicles and fire trucks unimpeded access.

As of posting time, the BFP reported no severe injuries or casualties, and damage assessment is ongoing.

Investigation into the cause of the fire continues, with relief operations being coordinated by the local barangay and fire officials.
