The death toll in floods caused by days of heavy monsoon rains in the Philippine capital and northern provinces has reached 36, officials said Thursday.

Four people were missing and at least 14 injured, according to reports from the Office of Civil Defence, police and local authorities.

Twenty-three of the victims drowned while nine were killed in a landslide, three died from electrocution and one from cardiac arrest, the officials said.

The deluge was the worst since 2009 when flash floods triggered by Tropical Storm Ketsana left 501 dead and missing in Manila and surrounding provinces.

Before the monsoon rains, Manila and the other areas were drenched last week by Typhoon Saola, which killed 53 people.
