KUALA LUMPUR, March 11 -- Search and rescue efforts for the missing Malaysia Airlines plane have been expanded beyond the flight path and the focus now is "on the West Peninsular of Malaysia at the Straits of Malacca," the airline said Tuesday in its latest statement.

"The authorities are looking at a possibility of an attempt made by MH370 to turn back to Subang. All angles are being looked at. We are not ruling out any possibilities," the company added.

"Apart from the search in the sea, search on land in between these areas is also conducted," said the airline, adding that analysis of the debris and oil slicks found at sea so far showed that they do not belong to MH370.

The Boeing 777 aircraft suddenly disappeared from radar early Saturday morning while carrying 227 passengers and 12 crew members from Kuala Lumpur to Beijing. Among the passengers 154 are Chinese.

The carrier said the plane, delivered in 2002, underwent maintenance 12 days before the ill-fated flight and "there were no issues on the health of the aircraft."
