Shiite rebels, known as Houthis, walk on the tarmac of the Sanaa International Airport in Sanaa, Yemen, Saturday, March 28, 2015. Yemen's President Abed Raboo Mansour Hadi, speaking at the opening session of an Arab summit in Egypt on Saturday, called Shiite rebels who forced him to flee the country "stooges of Iran," directly blaming the Islamic Republic for the chaos there and demanding airstrikes against rebel positions continue until they surrender.
