U.S. officials say the missing Malaysia Airlines jet with 239 people on board may have crashed into the Indian Ocean.
Flight 370 disappeared one week ago and investigators have yet to find any firm evidence of what happened. Theories include piracy and a catastrophic mechanical failure.
The U.S. officials tell American broadcast networks they have indications the jet is in the Indian Ocean, far west of its intended flight path.
White House spokesman Jay Carney said the United States may expand its search into the ocean because of what he calls "new information." He did not elaborate.

Indian military aircraft have also flown over the Andaman and Nicobar Islands -- more than 500 mostly uninhabited, heavily forested land masses.
Investigators believe the plane may have flown for several hours after disappearing from radar. They say the jet was sending electronic pings to a communications satellite.
