Yemen's embattled President Abedrabbo Mansour Hadi arrived Thursday in Riyadh, which is leading a coalition against Shiite rebels threatening his rule, the kingdom's official Saudi Press Agency reported.
Hadi, whose whereabouts have been unknown since the Huthi rebels and their allies closed in this week on the main southern city of Aden, where the president sought refuge after he fled the rebel-controlled capital Sanaa last month.
Yemen's acting foreign minister Riyad Yassin told reporters in Cairo that Hadi would take part in a two-day Arab summit to be held in Egypt from Saturday.
