ABU DHABI, United Arab Emirates (AP) - U.S. Secretary of State John Kerry is focusing on Iran and Syria during meetings in Abu Dhabi with Emirati officials. Kerry arrived in the United Arab Emirates on Sunday after a marathon but inconclusive negotiating session in Switzerland about Iran's nuclear program. The UAE is a valuable American partner in the Gulf. Like other Arab states in the region, the UAE is deeply concerned about Iran's nuclear ambitions. Kerry plans to return to Washington on Monday after his talks in Abu Dhabi.
