The Houthis acknowledged that guards fired three tear gas canisters into a crowded hangar in the capital, Sanaa, trying to end a protest by the migrants. A statement by the Houthi Interior Minister said at least 11 men from the security forces were detained over the incident, along with a number of senior officials who would be tried before court. The migrant community in Sanaa has called for an international probe into the tragedy, a demand backed by international rights groups. Some 900 migrants, most of them from Ethiopia, had been detained at the facility — including more than 350 inside the hangar. The site was run by the Passports and Naturalization Authority. At least 45 people were killed in the March 7, the militia said, including one who died of his wounds on Friday. More than 200 others were wounded. The migrants had been protesting and went on hunger strike against alleged abuses and ill-treatment at the detention facility, according to survivors and local rights campaigners. The Houthis Saturday claimed that the migrants were protesting to pressure the International Organization for Migration to transfer them.
