US President Barack Obama on Thursday said he updated the United States' Gulf Cooperation Council (GCC) partners on the negotiations toward a comprehensive deal to prevent Iran from obtaining a nuclear weapon. Obama said he was pleased that both sides agreed that "a comprehensive, verifiable solution that fully addresses the regional and international concerns about Iran's nuclear program is in the security interests of the international community, including our GCC partners." He was speaking at a press conference on Thursday evening at the conclusion of a summit with Gulf leaders at the presidential retreat at Camp David, Maryland. "Whether we reach a nuclear deal or not with Iran, we are still going to face a range of threats across the region, including its destabilizing activities, as well as the threat from terrorist groups," the president said. "So we are going to work together to address these threats, and much of the enhanced security cooperation that I have outlined will allow us to do precisely that. The US President stressed that the both sides discussed the conflicts in Syria and Yemen, especially combating ISIS terrorist organization, confirming importance of cooperation between the GCC and the United States in this regard. The US President welcomed the humanitarian truce announced by the Kingdom of Saudi Arabia, calling upon the Yemeni parties to return to the table of talks within framework of the United Nations efforts.
