Vice President Sara Duterte condemned Saturday the ambush that targeted Lanao del Sur Governor Mamintal "Bombit" Alonto Adiong Jr.

Duterte said "we should collectively reject this cowardly act of violence and demand that the perpetrators are immediately brought to justice."

Mayors of Lanao del Sur also released a statement describing the incident as "an attack against us and a travesty on the morals of the good people of Lanao del Sur."

"We seek the support and cooperation of all stakeholders including the leadership of BARMM, civilians, [and] law enforcement agencies in pursuit of a credible information and justice for our people and the victims," the statement read.

The mayors also called upon the national government to "immediately convene peace mechanisms to help in the identification and ultimate arrest of the perpetrators, and achieve justice for the victims."

"We call on the families of the perpetrators to show their sincerity in the call for justice by surrendering to the authorities their relatives involved in this dastardly act," the statement read.

Interior Secretary Benjamin “Benhur” Abalos, Jr. has vowed justice for the victims of the ambush and instructed the Philippine National Police to conduct a manhunt for those involved.
