Authorities said Zamboanga City has been receiving threats from lawless elements following the intensified operations of the military against the Abu Sayyaf Group.
The city was recently placed under red alert after a foiled jailbreak at the city jail involving the group of Abu Sayyaf leader Furuji Indama.
Speaking to ANC’s “Top Story,” Mayor Beng Climaco said the Abu Sayyaf Group could be behind the explosion.
Climaco said the blast could be part of a plot by the terrorist group to break 57 of their “high-value” comrades out of the city jail.
“We have received notices (from the intelligence community) that they are going to be rescued by their comrades, who are ready to die,” she said.
