Malaysia on Thursday abruptly scrapped a visa-free pact with North Korea over the assassination of Kim Jong- nam at Kuala Lumpur International Airport on Feb. 13. Malaysian Deputy Prime Minister Ahmad Zahid Hamidi said the move was motivated by concerns for national security, according to the Bernama news agency. The North has infuriated Malaysians by denouncing the police investigation after four suspects fled to Pyongyang while two others remain holed up in the embassy.
