With the exact location of Flight 370 still unknown, profound questions remain about what brought down the aircraft and why.

The Malaysian Prime Minister said authorities searching for missing flight MH370 have to assume beyond any reasonable doubt that the plane has been lost, with no survivors.

Rescuers are continuing their search for a Malaysia Airlines plane that disappeared with 239 people on board as Malaysia’s civil aviation chief said investigators were looking at “every angle”.

Investigators say an oil slick in the South China Sea is not from the missing Malaysian Airlines flight.
