Sensitive nuclear monitoring equipment has found no evidence that Malaysia Airlines Flight 370 exploded or crashed, the U.N. said Monday. Although the Vienna-based Comprehensive Nuclear Test Ban Treaty Organization uses seismic systems for detecting nuclear explosions, the equipment can also pick up explosions of "larger aircraft, as well as its impact on the ground or on water," Stephane Dujarric, Secretary-General Ban Ki-moon's spokesman, told reporters in New York. However, tests over the weekend had confirmed that "neither an explosion nor a plane crash on land or on water had been detected so far," Dujarric said Monday. Meanwhile, China's ambassador to Malaysia claimed Tuesday that none of the Chinese passengers aboard Malaysia Airlines Flight 370 were involved in the plane's disappearance last week.
