Today 20.7 million people, including 10.3 million children, are in need of urgent humanitarian aid in Yemen.
As the fighting continues, we are calling on the UK government to halt arms sales to Saudi Arabia.
We are extremely clear what we're asking for. We want Saudi Arabia to obey the rules of war, to stop killing civilians in Yemen, and to abandon a failed military strategy in favour of working towards a political solution.
Britain is providing welcome and life-saving aid to Yemen – but it also provides diplomatic cover. It is time for the Government to use this diplomatic relationship to push for an end to the conflict - and to demand our allies stop bombing children.
All sides in this conflict - including the Saudi-led Coalition, the Houthis, the Yemen Government, and everyone involved in the fighting, must come to the table and start to work for a negotiated peace, including Crown Prince Mohammed bin Salman.
