Our reporters have been to the Yemeni city of Saada, which is controlled by Houthi rebels. It has seen some of the worst battles since fighting broke out between the Iran-backed Houthis and the Saudi-led coalition in 2014. For civilians, particularly children, life has become hell on earth. Some people may find the images in this report disturbing. Just back from Yemen, FRANCE 24's reporter Cyril Payen speaks to us about the difficulties he and his team faced on the ground.
