Prosecutors on Tuesday filed rebellion charges against 11 individuals tagged in the terror rampage in Marawi City, including the mother of siblings leading the Islamic State-linked Maute group and a former mayor.

Ominta Romato "Farhana" Maute was among those charged before the Misamis Oriental Regional Trial Court in Cagayan de Oro City just days after the matriarch was arrested in Masiu, Lanao del Sur on Friday.

She is believed to be the financier of the Maute group, the police Criminal Investigation and Detection Group (CIDG) earlier said following a raid in her Marawi compound in December that yielded explosives.

Also among those indicted was former Marawi City Mayor Fahad Salic, who was arrested on Thursday at a checkpoint in Misamis Oriental.

A search operation in Salic's home in Cayagan de Oro City on Friday yielded four M203 grenades, a rifle loaded with 120 ammunition, 10 sachets of suspected 'shabu,' three plastic bags with suspected shabu residue, five cellular phones, three outside holsters, a pistol case, and a rifle case.

The other nine charged were Sumaya Bangkit Masakal, Radiea Tugosa Asire, Mariam Ibnu Abubakar, Zafeerah Rosales Musa, Nehreen Macaraya Abdul, Nora Moctar Limgas, Mardiyya Haji Ali, Sumayya Lawi Ali, and Noronisa Haji Camal.

In the charge sheet, prosecutors said the accused had conspired with several other still unidentified members of the ISIS-linked Maute group who are "now actively engaged in an armed rebellion against the government."

It said those charged "did then there willfully, feloniously help, support, finance, promote, maintain, cause, direct and have risen publicly and taken arms" to establish and Islamic State province in Mindanao.

State prosecutors identified their methods as “armed raids, sorties and ambushes, attacks against police, armed forces, army detachments as well as innocent civilians, hospitals, and schools," along with acts of murder, arson and planned destruction of private and public property."

Clashes between government troops and terrorists have continued for more than three weeks now, with the death toll at 286, among them 202 militants, 58 state forces and 26 civilians.

More than 200,000 residents have meanwhile fled Marawi City. Mindanao remains under martial law amid the ongoing government offensive.
