Clinton Presses Persian Gulf Countries on Iran

ABU DHABI, United Arab Emirates (AP) — U.S. Secretary of State Hillary Rodham Clinton is calling on Arab nations in the Persian Gulf that do business with Iran to step up enforcement of international penalties against Tehran.

Clinton tells reporters who traveled with her from Washington that Iran's nuclear program is "a serious concern." She says the U.S. expects its allies in the Gulf and elsewhere to "do everything within reason" to help ensure that the sanctions are in place.

She arrived Sunday in Abu Dhabi in the United Arab Emirates. It's the first stop of a three-nation tour that includes visits to Oman and Qatar.
