Asserting that the Malaysian government has been cooperating with the US on the missing aircraft, the White House said that the investigation has not reached a definite conclusion yet.
"We are finding that the level of cooperation with the Malaysian government is solid, and we are working closely with the Malaysians as well as our other international partners in this effort to find out what happened to the plane and why it happened," White House Press Secretary Jay Carney said.
"I have no update on the course of the investigation. It remains the case that, you know, we are not in a position yet to draw conclusions about what happened," he said, adding that
President Barack Obama is being constantly updated on the issue.
