South Korea is considering to expanda ban on liquids on all international airlines to tighten anti-terrorism measures starting in March, the Civil Aviation Safety Authority said on January 24.

South Korea currently bans passengers from carrying liquids that can be used in making explosive devices onto planes on routes to the United States only.

International Civil Aviation Organization has recommended expanded security guidelines for screening liquids, gels and aerosols that can be used in improvised explosive devices on all international flights.

The measure, which came in respond to the terrorist attack in the U.K. with liquid bombs in August last year, has since been in force in the U.K. and the U.S..

Under the new guidelines, passengers are not allowed to bring more than 100 ml of liquid in a container on planes, and the size of the container is limited to less than one liter.
