Vietnam is scaling back the search in Vietnamese waters for a Malaysian Airlines jetliner missing for four days, a senior Vietnamese official said.
"We still have plans to search with a few flights today, while other activities are suspended," Deputy Transport Minister Pham Quy Tieu, who heads the Vietnam search, told reporters. Tieu said searches by ships were being suspended.
He said Vietnam had asked Malaysian authorities for information about reports that the plane, carrying 239 passengers and crew, had changed direction after its last known contact on Saturday but it had yet to receive any response.
Meanwhile, China will add two planes to the search, the country's civil aviation chief said.
