Edmund Fitton Brown, the UK's Ambassador to Yemen between 2015 and 2017, told MailOnline that before the war, it was common for young girls, 'often below the age of 10', to be married to men many decades older than them. He said he recalled hearing of girls as young as eight being married. 'Part of the incentive was economic, easing financial burdens on the family. Also for protection and to create a family alliance.' 'All of these drivers have been growing stronger.'
