Metro Manila (CNN Philippines) – The Abu Sayyaf Group may be among the usual suspects, but its spokesperson said the group is not behind the deadly Davao blast on Friday.

Muammar Askali alias Abu Rami, a self-proclaimed spokesperson of the terror group, told CNN Philippines in a phone interview on Saturday that their group did not initiate the explosion.

"Kung sasabihin niyo grupo ko, ay hindi grupo ko [If you're saying that it's my group, it isn't my group]," said Abu Rami.

Defense Secretary Delfin Lorenzana earlier said the ASG could be behind the incident to retaliate against the military's ongoing operations targeted at the terror group in Sulu. Davao City Mayor Sara Duterte also said she was texted by the Office of the President that the group was behind the incident.

Abu Rami admitted he is clueless as to who carried out the explosion and how it was executed, but what he is sure of is those behind the blast share the Abu Sayyaf Group's extremist cause. He said a clear indication of this is that most of the victims of the explosion are Christians.
