Four people are feared dead after a plane went missing over the weekend.
The Cessna 340 plane, which was bound for the Philippines' capital Manila, vanished after taking off from Albay province southeast of the capital on Saturday morning with two Filipino pilots and two Australian passengers.
The fate of those onboard is still unknown and rescuers have been struggling to reach the slopes of the active volcano in the central Philippines where the small plane is believed to have crashed.
