Rescuers struggled through the night in heavy rain to dig out victims buried after a landslide triggered by monsoon rains toppled dozens of homes, killing at least 12 people.
The death toll from four days of torrential rainfall in the Manila area is now at least 46, officials said. Elsewhere in Asia, floodwaters killed dozens more people, including 40 in South Korea and five in Thailand.
Rescue workers in the Philippines searched under twisted walls and roofs for victims in the hillside housing development in Antipolo City, east of Manila. Defense Secretary Orlando Mercado, who heads the National Disaster Coordinating Council, said many people might still be missing in the collapse.
Elsewhere in the Manila area, 34 people died in floodwaters or landslides or were electrocuted in the heavy rains that began Sunday, officials said. Tens of thousands of homes were flooded, forcing the evacuation of 73,916 people in the Manila area and nearby cities.
Floods began receding in some areas on Wednesday, officials said, but monsoon rains and winds are expected to batter the Philippines for several more days.
In South Korea, tens of thousands of residents returned to their sodden, mud-caked homes and found only shattered debris after deadly flooding that left 40 people dead and 24 others missing.
In Thailand, five people died and about 1,000 were left homeless after five days of flash floods engulfed the low-lying coastal province of Chanthaburi, 130 miles southeast of Bangkok.
