Six Arab states on the Persian Gulf are considering a proposal to invite Iran to join in declaring the oil-rich region a nuclear-free zone.
Leaders of Bahrain, Kuwait, Oman, Qatar and Saudi Arabia joined UAE officials in Abu Dhabi Sunday under tight security for the two-day meeting.
Before the summit, the Gulf Cooperation Council's secretary-general (Abdul Rahman al-Attiya) said the group trusts Iran, but wants to ensure that a nuclear power plant is not built close to the waters of member states.
Iran is under intense international pressure to halt work on its suspect nuclear fuel program and allow inspectors full access to its nuclear sites.
The United States accuses Tehran of secretly trying to develop an atomic bomb, but Iran says its program is aimed at developing electricity.
