(Time) – It takes about a dozen hours by car to reach Sana’a, the besieged capital of civil war-struck Yemen, from the port city of Aden, at the southern tip of the Arabian Peninsula. You must bypass Taiz, the frontline city where fighting rages between a mosaic of loyalist forces, rebels and al-Qaeda jihadists. You must cross an incalculable number of military roadblocks controlled by any one of the multiple factions vying for control.
