A fire razed a four-door apartment complex along Campa Street, near España in Manila at around 9 p.m. on Saturday.
Another blaze occurring at around 3 a.m. the following day razed a row of houses and some establishments nearby.
Residents blamed the second fire on a still unidentified village official who allegedly turned on the main switch of an electrical post.
However, a fire officer clarified that the two fires were distinct and different from each other because they were sparked by different causes.
SPO1 Patrick Angeles of the Manila Fire Bureau said the two blazes reached the fifth alarm and were declared fire-out around 4:10 a.m.
The first fire originated from the apartment complex which was made of wood.
Arson investigators are still identifying the causes of the two fires.
Around ten houses were razed in the second fire while a number of boarders, mostly students, were displaced.
