American supermodel and activist Halima Aden has been announced as an ambassador for UNICEF USA, and will 'use her voice to engage young people across the US to support UNICEF's mission to put children first'.

The IMG model, born in a refugee camp in Kenya, commented 'When I was young, UNICEF gave me an education, empowering myself, my family and our community in the process. It's an honour to have this platform with UNICEF USA and I look forward to advocating for children around the world, just as others advocated for me'.
