South Korea declares highest security alert

South Korea's Ministry of Land, Transport and Maritime Affairs stated it is upgrading the security alert at Incheon, Gimpo, Gimhae, Cheongju and Jeju airports to the highest level this week to ensure safety during the G-20 Seoul summit (chosun, 08-Nov-2010). The red alert, the highest on the colour-coded scale, means 50% of passengers are screened by hand and 50% of carry-on luggage is opened and searched. It is the first time the alert has been raised for the country's major airports.
