The Senate Defence Committee will investigate a fire that razed the headquarters of the military's logistics command to determine if it was deliberately set.
It was the second time the building, which houses the military's records, had been burned down.
Committee chairman Senator Orlando Mercado said the military was guilty of 'gross negligence'. He called for officers who 'neglected their jobs' to be dismissed.
The duty officers at the time of the fire on New Year's Eve were reportedly drunk.
Mr Mercado said this was the second time in seven years that the building burned down and that, as in 1989, this year's fire resulted in the loss of 'vital records'.
Commodore Ruperto Andaya, chief of the logistics command, insisted that the destroyed documents could be replaced by duplicates.
