Following the death of Omar Maute and Isnilon Hapilon, top leaders of Islamic State-inspired extremists Maute group, questions now arise as to who will get the bounty on their heads.

Hapilon and Maute were killed in a military assault early Monday.

According to Armed Forces Chief of Staff Eduardo Año, "deserving" informants will undergo a process to claim the reward.

"It will undergo a process. Meron tayong mga informants na qualified and deserving to receive the reward. Susundan natin yung proseso na naayon doon sa US claim reward system," he said in a press conference Monday.

Defense Secretary Delfin Lorenzana earlier said the whereabouts of Hapilon and Maute, who were holed up in a building in Marawi City, were divulged by a female hostage who managed to escape.

"Yesterday, or the day before, there were these rescued hostages, I think it was a female, a woman, and she recounted to the troops that she talked to Maute or Isnilon and she confirmed the presence of Isnilon and Maute in that building," he said.

Last June, President Rodrigo Duterte offered a P10 million reward for the "neutralization" of Hapilon and P5 million each for brothers Abdullah and Omar.

The amount is on top of the $5-million (nearly P247 million) bounty that the U.S. Government had placed on Hapilon's head, and a separate P7.4 million standing bounty earlier offered by the Philippine government.

Altogether, total bounty on Hapilon's head is at P264.4 million.
