South Korea said Monday that it plans to reroute passenger flights over the Yellow Sea to avoid possible collisions with debris from a long-range rocket that North Korea plans to launch this month. The Ministry of Land, Transport and Maritime Affairs said it made the decision after learning that North Korea had informed China and Singapore of the flight path and other details of the launch. The International Maritime Organization said Monday that North Korea had informed it that it planned to launch a satellite between Dec. 10-22 during the hours of 7 a.m and noon. The North provided a list of dangerous coordinates where debris could fall. South Korean officials said they will reroute six Korean Air flights.
