Metro Manila (CNN Philippines, January 5) — Despite having a bloody history with the military, Moro National Liberation Front (MNLF) chairperson Nur Misuari was present during the change of command ceremony at the Armed Forces of the Philippines on Saturday.

Misuari was seen mingling with military officials, as well as with President Rodrigo Duterte during the event at Camp Aguinaldo in Quezon City.

In 2013, the Misuari-led MNLF stormed into the Zamboanga City intending to thwart the peace process then between the government and another separatist group, the Moro Islamic Liberation Front.

The standoff between government forces and Misurai's group led to the death of 189 guerrillas, 23 soldiers and police, and 12 civilians.

In 2018, the Pasig City Regional Trial Court released 96 members of the MNLF involved in the Zamboanga City siege. The court ruled that they have served all penalties for sedition. They were fined P5,000 each.
