South Korea on Thursday announced strengthened aviation safety measures following a fire on an Air Busan plane last month, saying the rules would include limiting the number and type of portable batteries allowed on the country's airlines.

Under the new safety measures passengers will be permitted to carry up to five 100 watt-hours portable batteries, while batteries over 160 watt-hours won't be allowed on board

South Korea's Air Busan will not allow passengers to keep power banks in luggage stored in overhead cabin bins, in what on Tuesday it called a preemptive measure after one of its planes was engulfed in flames last week.

Hong Kong expert says expansion of measure to other airlines will depend on further risk assessments by trade groups and carriers.
