(BBC News)  – After two years of war in Yemen and a Saudi-led blockade lasting 18 months millions of people are slowly starving – some are already dying for lack of food. One doctor in the Red Sea port city of Hudaydah is doing all she can to save them. In her 20 years as a doctor Ashwaq Muharram has never seen things so bad. “I’m seeing the same thing I used to watch on TV when the famine unfolded in Somalia,” she tells me. “I never thought I would see this in Yemen.” For years Muharram worked for international aid organisations, but most of them left when the fighting began in March 2015, and those that remain have drastically curtailed their activities.
