In this photo taken Tuesday, March 24, 2015, tanks seized recently by militiamen loyal to Yemen’s President Abed Rabbo Mansour Hadi take positions at the al-Anad air base in the southern province of Lahej, 60 kilometers (35 miles) north of Aden, Yemen. Hadi fled the country by sea Wednesday on a boat from Aden, as Shiite rebels and their allies advanced on the southern port city of Aden, where he had taken refuge, captured his defense minister and seized the city’s airport.
