In Yemen, officials say that U.S.-backed, Saudi-led airstrikes killed 28 civilians in the northern Hajjah province on Sunday. Officials say the victims were mostly women and children. Saudi Arabia has denied responsibility. This comes as Saudi diplomats are attempting to fend off calls for a U.N. Human Rights Council investigation into possible war crimes and crimes against humanity in the ongoing conflict in Yemen. A U.N. Human Rights Commission report has blamed the U.S.-backed, Saudi-led airstrikes for the majority of the civilian casualties.
