[Reuters] VX nerve agent, a chemical on a U.N. list of weapons of mass destruction, was used to kill the estranged half-brother of North Korean leader Kim Jong Un in last week's bizarre murder in a busy Kuala Lumpur airport, Malaysian police said on Friday.Kim Jong Nam died on Feb. 13 after being assaulted by two women who wiped the toxic chemical on his face as he prepared to board a flight to Macau at Kuala Lumpur International Airport.
Police arrested the two women - one Vietnamese and the other Indonesian - and a North Korean man last week. They are also seeking seven other North Koreans wanted in connection with the case, including a diplomat at the embassy in Kuala Lumpur.
South Korean and U.S. officials have said they believe North Korean agents assassinated Kim Jong Nam, who had been living in the Chinese territory of Macau under Beijing's protection.
