A military vehicle carries what is believed to be a Taepodong-class missile Intermediary Range Ballistic Missile (IRBM), about 20 meters long, during a military parade to mark the 100 birth of the country's founder Kim Il-Sung in Pyongyang on April 15, 2012. The commemorations came just two days after a satellite launch timed to mark the centenary fizzled out embarrassingly when the rocket apparently exploded within minutes of blastoff and plunged into the sea.
