SEOUL (Reuters) - South Korea's prime minister will preside over a national security council meeting on Wednesday morning to discuss the suspected murder of the North Korean leader's estranged half-brother in Malaysia, his office said.

A South Korean official also said they believed he had been murdered, without giving further details.
Kim Jong Nam, who was estranged from young North Korean leader Kim Jong Un, was known to spend a significant amount of his time outside North Korea and had spoken out publicly against his family's dynastic control of the isolated state.
South Korea is acutely sensitive to any sign of potential instability in its impoverished and nuclear-armed neighbor, with which it remains technically in a state of war.
Malaysian police said the dead man, 46, held a passport under the name Kim Chol. Kim Jong Nam has been caught in the past using forged travel documents.
Malaysian police official Fadzil Ahmat said on Tuesday the cause of Kim's death was not yet known, and that a post-mortem would be carried out. Kim had been planning to travel to Macau on Monday when he fell ill at the low-cost terminal of Kuala Lumpur International Airport (KLIA), Fadzil said.
The U.S. government sources said it was possible that Kim Jong Nam had been poisoned.
