LONDON: For more than two years after Mohammad Al-Shami was detained by the Houthis, his family and colleagues were given virtually no indication of what had happened to him. There was no information about his condition and no proof of life, despite repeated requests from the UN. Then came word that he was dead, and Arab News has learned that he has been dead for a year and a half. Al-Shami, a Yemeni employee of the UN Human Rights Office, had been detained by the Houthi authorities since June 6
