5. Airport security heightened to the highest level for the Nuclear Security Summit

With 2012 Seoul Nuclear Security Summit(26~27th) ahead, the security level of Korea's major airports will be heightened to the highest level.
On 15th, Ministry of Land, Transport and Maritime Affairs announced that for securing safety of airports and airplanes, the security levels of Incheon, Gimpo, Gimhae and Cheongju airports will be raised to 'Orange'(alert level) between 19th to 22nd, and further raised to 'Red' between 23rd to 27th.
The airport security level is classified into 5 levels such as Green→Blue→Yellow→Orange→Red.
As a result of heightened security level, the time taken for the security check will be increased because of stricted check for passengers, baggages, luggages, air cargoes, etc.
For this reason, at the major aiports, there will be additional placements of security check personnel and guides to minimize the inconvenience of the passengers.
Ministry of Land, Transport and Maritime Affairs requested for public cooperation saying, "There will be inconvenience of passengers because of stricted security check, but it is necessary measure to be taken for the international event where leaders of 57 nations(including international organizations) will participate"
