U.S. President Barack Obama says he will work with U.S. allies to address Iran's "destabilizing" activities" in the Middle East.
The White House said Obama told Sultan Qaboos, the leader of Oman, in a phone call on April 6 that Washington would work with Oman and "other regional partners to address Iran's destabilizing activities in the region."
Oman is a member of the Gulf Cooperation Council, which opposes Iran's alleged involvement in support of the rebel Huthis in Yemen.
Oman and other Arab states also accuse Iran of fueling proxy battles that have destabilized Syria, Iraq, Lebanon, and Bahrain.
Obama has called in recent days several Gulf state leaders and invited them to come to Washington for talks on regional matters and Iran's controversial nuclear program and the proposed agreement between Tehran and six world powers to curb that program.
