South Korea prepared for North Korea

While North Korea isn't backing away from threats of nuclear war, neighboring countries are taking precautionary measures for a possible missile test launch.

South Korea's presidential office told reporters Sunday that they take Pyongyang's surprise warning to foreign embassies and international organisations there to evacuate before April 10 as a sign that North Korea may test-fire its missile that day.

"We're thoroughly preparing for this, leaving all possibilities open," said Kim Jang-Soo, chief of the National Security Office, during a meeting at the presidential office, according to spokeswoman Kim Haing.
