Rep. Park Jie-won, who heads the minor People's Party, on Monday urged the Malaysian government to demand that North Korea extradite the suspects linked to the alleged assassination of the North Korean leader's half-brother in order to carry out a thorough investigation.
Kim Jong-nam, the eldest son of late North Korean leader Kim Jong-il, was killed at a Kuala Lumpur airport last week. Malaysian police said Sunday that they have identified four more North Korean nationals as suspects in the case, who reportedly left the Southeast Asian country and fled to Pyongyang.
