Four people were killed in the southern Philippines early Tuesday as a tropical storm unleashed heavy rain and triggered deadly landslides, police said. Tropical Storm Sanba slammed the east coast of the main southern island of Mindanao Tuesday with gusts of 75 kilometres (47 miles) an hour. The heavy rain triggered landslides that hit mountain villages outside the mining town of Carrascal - 760 kilometres south of the capital Manila - killing four people, municipal police chief James Alendogao told AFP.
