Malaysia Airlines Flight 370 went down over the southern Indian Ocean, Malaysian Prime Minister Najib Razak said Monday, citing a new analysis of satellite data by a British satellite company and accident investigators. The announcement appeared to rule out the possibility that anyone could have survived whatever happened to the aircraft, which vanished more than two weeks ago with 239 people aboard. As Razak spoke, airline representatives met with family members in Beijing. “They have told us all lives are lost,” one relative of a missing passenger told CNN.
