U.S. Secretary of State Rex Tillerson has left the Persian Gulf region after four days of talks to help mediate a dispute between Qatar and Saudi Arabia and its allies.
Tillerson on July 13 declined to comment after meeting Qatar's emir, Sheikh Tamim bin Hamad al-Thani, in his second stop in the tiny Gulf Arab state during his trip to the region.
Saudi Arabia, Bahrain, the United Arab Emirates, Egypt, and other countries broke all diplomatic and commercial ties with Qatar over its alleged funding for Islamic extremists and its close ties to regional rival Iran.
The four Arab states set a list of 13 demands on Qatar and threatened further sanctions against the country if it fails to comply.
Qatar denies the allegations and says they're an attempt to infringe on its sovereignty.
A day earlier, Tillerson held talks in the Saudi Red Sea city of Jeddah with ministers from the four Arab countries without word of a breakthrough.
On a first stop in Qatar, Tillerson signed a U.S.-Qatari accord on terrorism financing in an effort to help ease the crisis, but the Saudis and their allies said it was not enough to ease their concerns.
Diplomacy could now turn to the Europeans. French Foreign Minister Jean-Yves Le Drian is scheduled to travel to the region during the weekend.
Similar trips were made by Le Drian's counterparts from Germany and Britain in recent weeks.
