Over 150 human rights and press freedom groups are calling on the United Nations to help save four Yemeni journalists who were sentenced to death last month on charges of “spying” and “spreading false news.” Amnesty International has called the charges against the journalists, who have been in prison for the last five years, “trumped-up.” The sentence was handed down by the criminal court in the Houthi-controlled capital Sana’a, but the Committee to Protect Journalists says journalists in Yemen face threats from all factions: Houthis, the Saudi-led coalition and various militia.
