KUALA LUMPUR, Malaysia (AP) — One day after Malaysia revealed that VX nerve agent was used in a bizarre killing at the Kuala Lumpur airport, police said Saturday that they have raided a condominium and were awaiting lab results on what they found. The public poisoning of Kim Jong Nam, which took place amid crowds of travelers in a budget airport terminal, has boosted speculation that North Korea dispatched two killers to take out an outcast member of the ruling family. Senior police official Abdul Samah Mat, who is handling the investigation, did not specify what authorities found there, but said the items were being tested for traces of any chemicals. North Korea never signed that treaty, and has spent decades developing a complex chemical weapons program that has long worried the international community.
