Yemenis walk through the main gate of the old city of Sanaa on October 10, 2014, one day after a powerful suicide bombing, targeting a gathering for supporters of the Shiite insurgent Huthi group, ripped through the Yemeni capital, killing at least 47 people and plunging the violence-plagued country into further turmoil after weeks of political deadlock. Sign hung on top of the gate reads: "God is the greatest, death to America, death to Israel, curse the Jews, victory to Islam".
