A Saudi-led coalition backing Yemen's government will not allow rebel-controlled air and sea ports to reopen until a better system is created to prevent weapons being smuggled from Iran. The coalition tightened its two-year blockade after a ballistic missile was fired at Riyadh airport. Iran denied arming Houthi rebels, and said the missile launch was ‘an independent action’ in response to coalition ‘aggression’. 2,000+ have died since April from cholera, and 3,500 cases are being treated daily. The blockade will undo efforts to curtail its spread. 27,000 children a month are treated for severe and acute malnutrition. With no aid deliveries, nutrition supplies will run out within two months, affecting the treatment of 400,000 children over the coming year. The children will bear the scars of this conflict long into the future. Civilians are the only people paying the price for political wrangling.
