No plan for immediate retaliation against Israel: Iranian official

Iran has reportedly signalled it has no plans for immediate retaliation, after what several sources suggest was an Israeli attack on its territory in the latest apparent tit-for-tat exchange. It has sparked fears that tensions between the two rivals could morph into a wider conflagration. America's top diplomat has refused to comment on reports of an attack on central Iranl. But Tehran said there is little damage and no need for immediate retaliation. Sarah Coates and Benji Hyer report.
