Korea plans to strengthen its oversight of low-cost carriers (LCCs) and impose strict penalties on airlines failing to meet enhanced operational safety standards, the government said Thursday, following last month's Jeju Air crash.

South Korean authorities are still investigating the cause of the recent air disaster at Muan International Airport. Some are blaming a concrete embankment at the end of the airport runway, which will now be removed.

Seven airports will also have their runway safety areas adapted following a review of all South Korea's airports that was carried out after the crash - the deadliest in the country's history.

The Ministry of Land, Infrastructure and Transport said it had ordered plans for localizers to be placed underground or replaced with lightweight metal structures within the year
