[update of earlier story] Iraq's Sunni Arab neighbours are to urge Sunnis to vote in upcoming Iraqi elections to ensure the minority plays a role in Iraq and curb Shi'ite Iran's rising influence in the country, diplomats say. They said a conference of Sunni-dominated Egypt, Jordan, Kuwait and Saudi Arabia on Thursday would stress Iraq's Arab nature and warn against outside efforts to influence the vote in a communique already agreed by their foreign ministers. [...] In an interview published on Thursday, Jordan's King Abdullah warned Iraq's unity was at stake. (Reuters)
