Malaysia plane: 100 search flights and still nothing

Malaysia will not give up on the search for missing flight MH370, its prime minister said as he visited the search hub in Perth.

Prime Minister Najib Razak's comments came, as one aviation expert warned the cost of the operation could be "ten times" larger than the one that followed the Air France disaster.

The BBC's Jon Donnison added: "Over the past two weeks there have been almost 100 search flights and still nothing. The costs are massive."
