KUALA LUMPUR, Malaysia — The astonishing assassination of North Korea leader Kim Jong Un's half-brother rippled across Asia on Wednesday as Malaysian investigators scoured airport surveillance video for clues about the two female assailants and rival South Korea offered up a single, shaky motive: paranoia.
Kim Jong Nam, 46, was targeted Monday in a shopping concourse at Kuala Lumpur International Airport, said a senior Malaysian government official, who spoke on condition of anonymity because the case involves sensitive diplomacy. He had not yet gone through security.
Kim, who died on the way to a hospital, told medical workers before he died that he had been attacked with a chemical spray, the official said.
South Korea's spy service said Wednesday that North Korea had been trying for five years to kill Kim Jong Nam. But the National Intelligence Service did not definitely say that it was North Korea, just that it was presumed to be a North Korean operation, according to lawmakers who briefed reporters about the closed door meeting with the spy officials.
The NIS cited Kim Jong Un's alleged "paranoia" about his half-brother. Still, the NIS has a history of botching intelligence on the North and has long sought to portray the North's leaders as mentally unstable.
In Malaysia, police were searching for clues in the CCTV footage from the airport, said Selangor police chief Abdul Samah Mat. The airport is in Selangor near Kuala Lumpur.
Kim Jong Nam was estranged from his younger brother, the North Korean leader. Although he had been tipped by some outsiders as a possible successor to his dictator father, others thought that was unlikely because he lived outside the country, including recently in Macau, Singapore and Malaysia.
He reportedly fell further out of favor when he was caught trying to enter Japan on a false passport in 2001, saying he wanted to visit Tokyo Disneyland.
