North Korea on Friday defied warnings from the international community and launched a rocket — which then exploded about a minute after takeoff — scattering debris over the Yellow Sea off South Korea.

The North's three-stage rocket "was airborne for more than a minute before it broke apart," Defense Minister Naoki Tanaka told reporters at 8:32 a.m., less than an hour after it was launched around 7:40 a.m.

At a separate press briefing, a South Korean military officer said the rocket exploded just one or two minutes after liftoff and about 20 pieces plunged into the sea, Kyodo News reported.
