Yagi registers as the world’s second-most powerful tropical cyclone this year and has caused power outages in more than 800,000 homes

Asia’s strongest storm this year, Super Typhoon Yagi, made landfall in northern Vietnam on Saturday, the meteorological agency said, killing at least four people after tearing through China’s island of Hainan and the Philippines.

Super Typhoon Yagi hit island districts of north Vietnam at about 1pm (0600 GMT), generating winds of up to 160kph (99mph) near its centre, having lost power from its peak of 234kph (145mph) in Hainan a day earlier.

The government said that, as of 5pm, four people had died and 78 had been injured by the typhoon. At least another dozen were missing at sea, according to state media.

Yagi had already claimed the lives of at least two people in Hainan and 16 people in the Philippines, the first country it hit, having formed east of the archipelago earlier in the week.
