MANILA, Philippines -- Interior Secretary Mar Roxas said the cause of the blast at Two Serendra condominium in Taguig City Friday night remains unknown.
The explosion left three dead and five others injured.
Roxas added three teams of bomb-sniffing dogs were used to scour the blast site and so far, there was no indication a bomb caused the explosion.
The secretary, however, was quick to point out they are not ruling out anything until the probe is done.
Meanwhile, motorists were advised to avoid the Mckinley Parkway road because it is closed to traffic due to ongoing investigations although surrounding establishments are open to consumers.
