A storm bearing down on the Philippines’s largest island has been upgraded to super typhoon status, with one region already experiencing “life-threatening conditions”.

Typhoon Fung Wong will bring sustained winds of 185 km/h (155mph) and torrential rain to several areas on Sunday, according to the country’s meteorological service, Pagasa.

The BBC’s Jonathan Head is on Luzon Island, and says the region is braced for an “absolutely massive storm”.
