North Korea's leader Kim Jong-un's brother reportedly was assassinated at an airport in Malaysia. South Korean media reported Kim Jong-nam was killed at Kuala Lumpur airport after being attacked by two women with "poisoned needles." The two women, who still remain at large, are believed to North Korean agents. Jong-nam was once considered heir before falling out of favor with his father Kim Jong-il, after attempting to enter Japan on a forged passport. Since then, he has lived in virtual exile, namely in the Chinese territory of Macau.
