The United Nation says the humanitarian situation in Yemen is now deeply precarious, and any further destabilization could provoke a famine. The warning from the UN's World Food Program comes as pressure mounts on a month-old ceasefire in the port city of Hodeida, which is a vital gateway for aid supplies to Yemen. In the last few days, a wheat storage facility and a camp for displaced people have come under fire. The UN humanitarian coordinator Lise Grande told the BBC that the food situation across the country remain desperate.

He said I'm tired because he's slept poor the previous night. He talked obsessively to his young copilot about a colleague's criticism of his performance as a trainer which deeply upset him and his plans to resign. As the plane came into land, his behavior was impulsive and inappropriate, it's said, and he made a series of mistakes which proved fatal for so many of those on board.
