The Armed Forces of the Philippines lay siege to the Peninsula Manila after soldiers led by Senator Antonio Trillanes stage a mutiny.

The Manila Peninsula siege occurred on November 29, 2007, at The Peninsula Manila hotel in Makati, Philippines. Senator Antonio Trillanes IV, Brigadier General Danilo Lim, and 25 other Magdalo (mutineers) officers walked out of their trial and marched through the streets of Makati. The mutineers called for the ousting of President Gloria Macapagal Arroyo, and seized the Rizal function room on the second floor of the Manila Peninsula Hotel along Ayala Avenue. Former Vice-President Teofisto Guingona, Jr. as well as some of the soldiers from the Armed Forces of the Philippines joined the march to the hotel.

After several hours, Trillanes and Lim surrendered to government forces after a military armored personnel carrier barged into the glass door of the hotel lobby and the hotel walls and windows sustained weapons damage. Trillanes and the mutineers were arrested while several journalists covering the event were detained. The journalists were subsequently released.

The Armed Forces of the Philippines (AFP) (Filipino: Sandatahang Lakas ng Pilipinas) are the military forces of the Philippines. It consists of three main service branches; the Army, the Air Force, and the Navy (including the Marine Corps). The President of the Philippines is the Commander-in-Chief of the AFP and forms military policy with the Department of National Defense, an executive department acting as the principal organ by which military policy is carried out, while the Chief of Staff of the Armed Forces of the Philippines serves as the overall commander and the highest-ranking officer in the AFP. The Philippine Coast Guard also serves as an attached service of the AFP in wartime. Military service is entirely voluntary.
