FILE - In this Oct. 23, 2012, file photo, Emir of Qatar Sheikh Hamad bin Khalifa al-Thani waves to the crowd as he and and Gaza's Hamas prime minister Ismail Haniyeh, not pictured, arrive for corner-stone laying ceremony of a Qatari funded rehabilitation center in Gaza City. The emir of Qatar received a hero's welcome in Gaza on Tuesday, becoming the first head of state to visit the Palestinian territory since the Islamist militant Hamas seized control there in 2007. When President Barack Obama meets over the next month with leaders from Mideast and other regional nations, he will have a timely opportunity to try to rally the Syrian opposition's main backers around a unified strategy to oust Syrian President Bashar Assad. Jordan, Turkey, Qatar and the United Arab Emirates _ whose Sunni Muslim leaders will meet separately with Obama starting April 16_ are all believed to be arming or training rebel forces seeking to overthrow Assad's regime.
