The South Korean military plans to inform North Korean soldiers and civilians about the murder of their 'merciless' leader's half-brother through loudspeakers along the border, Yonhap News Agency said quoting a government official.
Cross-border loudspeaker broadcasts are among the tools used by Seoul to carry out nonmilitary psychological warfare against Pyongyang.
The fact that five North Korean men, including one who had been staying in Kuala Lumpur with his family, were involved in the case suggests that Pyongyang was behind the killing of the eldest son of late North Korean leader Kim Jong-il, Yonhap reported Tuesday.
Five suspects, all identified as North Korean nationals, were near the scene of the attack committed by a Vietnamese woman and an Indonesian woman at Kuala Lumpur International Airport on Feb. 13, the news agency suggested.
Only one of the five are in custody, with Malaysian police saying the remaining four North Koreans, who had entered Malaysia separately, left the country shortly after the attack through the same airport.
Another step the international community could take is sending case of Kim's murder to the International Criminal Court, where a South Korean activist group had already submitted a petition to look into the brutal execution in 2013 of Kim Jong-un's uncle, Jang Song-thaek, and other charges of genocide.
