MANILA – President Rodrigo Duterte on Friday threatened to have a former Marawi City Mayor killed for his alleged involvement in the ongoing siege in the conflict-stricken city.

Speaking before troops in Sultan Kudarat, Duterte singled out former Marawi City Mayor Omar Solitario Ali, whose name is on the arrest order released by the Department of National Defense this week.

The list names 186 terrorists, spies, couriers and other associates linked to attacks in Marawi City and other parts of Mindanao.

The President recalled his recent phone call with Ali, a member of his political party Partido Demokratiko Pilipino- Lakas ng Bayan (PDP-Laban), where he gave the latter a mouthful.

“Sabi ko, p*******, ano ka ba? Kampi ka sa gobyerno o kalaban tayo? Kasi sabi ko pinapahuli ka ni [Defense Secretary Delfin] Lorenzana, p**** i**, ipapatay talaga kita,” Duterte said in a speech before soldiers at a military camp in Sultan Kudarat.

Ali’s brother, Fajad Salic, was arrested Wednesday on rebellion charges. Salic, also a former Marawi City mayor, was also included in the arrest order.

Duterte said he had told Ali to first clear his name before Defense Secretary and martial law administrator Delfin Lorenzana before they could continue communicating with each other.

“Sabi ko, kung ma-areglo mo si [Lorenzana], tapos ma-clear mo ‘yung pangalan mo, hindi ka talaga kasali diyan sa p**** i**** gulo na ‘yan, bago pa tayo mag-usap,” he said.

In the arrest orders, Lorenzana said members of terrorist group committed rebellion by "publicly taking arms against the duly constituted authorities for the purpose of removing Mindanao from the territory of the Government of the Philippines" and attempting to place the island under the control of international terror group Islamic State.

The personalities were also subject to arrest for "indiscriminately killing, kidnapping, perpetuating bombings in Marawi City and some parts of Mindanao, and sowing terror in the populace," the document read.

Salic and Ali are just some of the locals being accused of backing the entry into Marawi City of local terrorist groups who have pledged allegiance to ISIS.

Government had earlier said the terrorist Maute and Abu Sayyaf groups, allegedly aided by foreign jihadists, were planning to establish an Islamic State wilayat (province) in Mindanao.

Lorenzana issued the arrest order through his authority as administrator of martial law in Mindanao, which Duterte had declared on May 23.

The president issued the proclamation and suspended the privilege of the writ of habeas corpus in Mindanao hours after clashes erupted between government forces and extremists on the same day.

In his speech, Duterte again lambasted locals for supposedly allowing and harboring extremists.

“Ang ayaw ko, nagalit ako sa mga Maranao kay ganito. Bakit ninyo pinayagan pumasok ang ISIS?” he said.

Clashes in Marawi City began as state forces were attempting to arrest top Abu Sayyaf leader Isnilon Hapilon. Local terror groups had planned attacks days earlier, as seen in a video obtained by the military.

More than 200,000 residents have fled the city, while at least 209 have died, among them 134 terrorists, 45 troops and 30 civilians.
