On Sunday, Malaysia's Kuala Lumpur International Airport has declared that it is completely safe after authorities completed their investigation and containment of the airport after a deadly nerve agent was used to kill North Korean political exile Kim Jong-Nam, the half-brother of North Korean Leader Kim Jong-un. Malaysia's Deputy Health Minister denies the existence of the illegal nerve agent "VX" in Malaysia suggesting it was brought by possible third parties targeting Kim Jong-Nam.

According to CNBC -- citing Selangor State Police Chief Abdul Samat Mat -- Kuala Lumpur International Airport Terminal 2 is cleared of all hazardous material and possible contamination. The police chief said in a press conference in the airport that Terminal 2 is now classified as a "safe zone."

Surveying and sweeping the site were the Malaysian Police Forensic Team, Fire Department and the Atomic Energy Licensing Board. Despite the possible spread of the nerve agent "VX", Malaysian authorities report airport staff and in-airport medical staff Kim Jong-Nam approached as he suffered from the attack were neither harmed nor contaminated by the nerve agent.

According to The Star Malaysia, citing Malaysian Deputy Health Minister Datuk Dr Hilmi Yahaya, the nerve agent "VX" -- declared an illegal weapon of mass destruction by the United Nations -- does not exist in the Asian country. Its properties allow transport of the substance in small amounts. Dr Hilmi said "it is the first time we are coming across VX."

Dr Hilmi said "VX" could induce paralysis in a matter of minutes targeting the body's nerve system. Breathing failure along with succeeding multiple organ failures occur once inhaled.

Two women possibly attacked Kim Jong-Nam according to collected security camera footage. A woman had forcefully covered Kim Jong-Nam's breathing passages with a cloth authorities believe contains VX. Further footage shows the political exile rubbing his eyes. He was declared dead before arriving in a hospital.
