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.

The Ministry of Land, Infrastructure and Transport has announced a guideline prohibiting the stowage of portable batteries and e-cigarettes in overhead bins in reaction to suspicions that a huge Busan Air blaze was caused by a power bank.

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.
