Iran will attend a conference of key powers including the US this week that will focus on stabilizing Iraq, a meeting Baghdad said might be a turning point for regional cooperation in easing the violence.Iraq’s Foreign Minister Hoshiyar Zebari said on Sunday there was a "high possibility" arch foes Tehran and Washington would hold bilateral talks at the May 3-4 conference in Egypt, although not necessarily at the ministerial level.US Secretary of State Condoleezza Rice, who will attend the conference in the Red Sea resort of Sharm el-Sheikh, said she would not rule out the possibility of meeting directly with Iran's foreign minister, Manouchehr Mottaki.“But what do we need to do? It’s quite obvious,” she told ABC television in the US.“Stop the flow of arms to foreign fighters. Stop the flow of foreign fighters across the borders.Stop stirring up trouble among militias that then go and kill innocent Iraqis. It’s quite clear what needs to be done.”Tehran said its delegation headed by Mottaki would have the “aim of helping the Iraqi nation and government”.Washington accuses Iran of destabilising Iraq and US officials say Rice would probably limit any discussions to this.
