MANILA, Philippines, Oct. 31 (UPI) -- The Philippines' fourth typhoon in weeks killed 12 Saturday before moving into the South China Sea toward Vietnam, authorities said.
Most of the victims were killed by trees and debris falling on their homes after Typhoon Mirinae made landfall east of Manila, The Philippine Star reported Saturday.
The typhoon soaked the island nation with as much as 5.8 inches of rain and destroyed unstable houses near the coast, authorities said.
"We saw many shanty-type houses that had been washed away and residents frantically try to get hold of their household material," videographer James Reynolds told CNN by phone from Manila.
Mirinae, known locally as "Santi," was downgraded to a tropical storm as it moved into the South China Sea. It was expected to hit Vietnam in about 48 hours.
The typhoon was the fourth in a month. Since late September, typhoons Ketsana, Parma and Lupit combined killed more than 850 people, with Ketsana delivering the Philippines heaviest rainfall in 40 years. Thousands of people are still living in evacuation centers, officials said.
