Manila, Philippines ? President Gloria Macapagal Arroyo ordered an independent probe into a failed military mutiny.

Nearly 300 mutinous troops who seized a Manila shopping and apartment complex demanding the government resign gave up and retreated peacefully after some 19 hours.

Arroyo vowed Monday to punish the plotters and ordered an investigation into what caused the uprising that shook her presidency.

In a state of the nation address, Arroyo assured the country that she remains in control. The mutineers said they were protesting alleged corruption and misconduct within the military.

“I am constituting an independent commission to investigate the roots of the mutiny and the provocation that inspired it,” she told the Congress, which responded with a standing ovation.

“Such actions are deplorable and will be met with the full force of law,” she added.

Arroyo traveled to Congress aboard a helicopter and about 3,000 police officers and sharpshooters deployed outside the Congress building for her speech Monday.
