"Oxfam said on Tuesday that the Saudi-led coalition carrying out airstrikes against Houthi rebels has contributed to an extra three million Yemenis being denied drinking water. This means, according to Oxfam, that at least 16 million out of a population of 24 million do not have access to clean water and sanitation. The water shortage has brought a genuine threat of potentially life-threatening illnesses becoming widespread, including malaria, cholera and diarrhoea, Oxfam said." (thanks Amir)
