Yemen is suffering the world's worst cholera outbreak in the midst of the world's largest crisis, said the heads of three of the world's biggest humanitarian organisations. A vicious combination of war, cholera and hunger has left 80 per cent of Yemeni children in need of "immediate humanitarian assistance." Anthony Lake, executive director of Unicef, the United Nations children's agency, David Beasley, executive director of the World Food Programme, and Dr Tedros Adhanom Ghebreyesus, director-general of the World Health Organisation, travelled to Yemen to see the scale of the suffering in the country. In a joint statement released at the end of a two-day visit, they said Yemen - which was already one of the poorest countries in the world before the civil war started two years ago - was suffering a catastrophe at every level, with widespread acute malnutrition, impending famine, and much of its infrastructure destroyed. <span style='color: rgb(51, 51, 51); font-family: Roboto, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px; background-color: rgb(249, 249, 249);'>Cholera has claimed 1,900 lives since April, with 400,000 suspected cases across the country, according to the UN and the International Committee of the Red Cross.</span>That number is expected to reach 600,000 by the end of the year.
