Arab Official in Washington: "The US & Obama are the only ones who can put Qatar in its place."

(WSJ) WASHINGTON—"The U.S.'s closest Arab allies are jointly pressing President Barack Obama to take the lead in bridging the Middle East's divisions over Syria, traveling to Washington to personally drive home their fears that some of the region's other leaders are strengthening radicals and prolonging President Bashar al-Assad's rule.

"The U.S. and the president are the only ones who can put Qatar in its place."They are also concerned that aid from Qatar has bolstered the Al-Nusra Front, a powerful Syrian militia fighting Mr. Assad's forces, which the U.S. has designated as a terrorist organization.
Qatari officials, who have publicly denied supporting the Al-Nusra Front, declined to comment Thursday. A Turkish official denied Prime Minister Recep Tayyip Erdogan's government was favoring Islamist parties in Syria or anywhere else in the region.
