Iran Press/ Asia: The Hong Kong Government Flying Services says it was notified of an explosion at 4:05 pm (08:05 GMT) on an oil tanker in waters 300km (186 miles) to the east of Hong Kong.
The cause of the blast was unclear as of Saturday night, a government spokesperson said.
A fire on the oil tanker was put out by the time rescuers arrived, AFP news agency quoted the spokesperson as saying, adding the ship had lost its mobility. Authorities were unable to confirm if there were oil spills because of poor visibility after nightfall.
Authorities dispatched a fixed-wing aircraft and two helicopters to rescue seven crew members reported to be injured.
One man had died by the time rescuers arrived at the Panama-registered ship, the 5,547-tonne Chuang Yi. 219
