Inspector Wally Kasuyo, spokesman of the city police, said no one was killed or injured in the blast.
Kasuyo said the explosives could have been hurled at the terminal to scare drivers competing with a rival organization operating a terminal nearby.
"Obviously it was not meant to hurt or kill someone. The competing groups of drivers were mostly related to each other both by blood and affinity," Kasuyo said. – John Unson
