North Koreans do not appear to be aware of the death of leader Kim Jong-un's half brother as Pyongyang has tightened control over the inflow of outside information, sources here said on Friday.
But despite the regime's surveillance, "it is only a matter of time before the news spreads as more North Korean residents have secret access to outside information," they said.
Kim Jong-nam, the eldest son of late former leader Kim Jong-il, was killed in an airport in Malaysia on Monday after being attacked by two women who are suspected to have used some sort of poison, Yonhap News Agency reported.
It has yet to be confirmed whether North Korea was behind the latest killing, but Seoul's intelligence agency said that Kim Jong-un has issued a "standing order" to murder his sibling after he assumed power in 2011.
Many North Koreans neither seem to be aware of Kim's death nor know who Kim Jong-nam is, the sources said, in an indication that shows the regime has controlled all information about him.
"I've never heard about that news," said a source who is living in North Korea's provinces bordering China. "Isn't Kim Jong-un the eldest son of late former leader Kim Jong-il?
US-based media Radio Free Asia (RFA) said that North Korean residents including party officials in provincial areas do not know that the half brother of the current leader was killed ahead of the 75th birth anniversary of his late father.
South Korea's military plans to use loudspeakers along the inter-Korean border to inform North Koreans of Kim's killing in a bid to reveal the brutality of the North's regime, government sources said.
Kim Jong-nam was once viewed as the heir apparent, but he had been living in other countries for years after apparently falling out of favour with his father for attempting to enter Japan with a fake passport in 2001.
The latest case marked the most high-profile death under the Kim Jong-un regime since the execution of Jang Song-thaek in December 2013, the once-powerful uncle of the incumbent leader.
Malaysian police have arrested three suspects including two women in connection with the death.
The results of an autopsy on his body are expected in coming days.
