A member of the Saudi forces stands to attention during a visit by Yemeni Prime Minister Khaled Bahah at the Saudi-led coalition military base in Yemen's southern embattled city of Aden on September 28, 2015. Since Bahah's return from exile on September 16, 2015, his government is conducting the country's business from Aden, and is aiming to reinforce fighters supporting Yemeni President Abedrabbo Mansour Hadi, battling Shiite Huthi rebels in the central region.
