KUALA LUMPUR, Malaysia (AP) - Malaysia's transport minister says the search for a missing airliner is being expanded westward only because it's still missing, and not because of any new information about the disappearance.
The international search expanded today further into the Indian Ocean amid signs the aircraft may have flown on for hours after its last contact with air-traffic control.
A U.S. official says the Boeing 777 sent signals to a satellite for four hours after the aircraft went missing early Saturday.
Vietnam says it has been asked by Malaysian authorities to consider sending planes and ships to the Strait of Malacca, also to the west of Malaysia.
Meanwhile, China has urged Malaysia's government to release any information it has. Today's appeal by the Foreign Ministry reflects growing frustration among Chinese officials over mixed and conflicting information about the plane, which vanished nearly a week ago with 239 people aboard.
