CAIRO/RIYADH (Reuters) - The election of a moderate Iranian president could help rein in hostility between Tehran and its Arab neighbours, but many Arabs doubt he can end a sectarian confrontation that has been inflamed by war in Syria.
Hassan Rohani, a Shi'ite cleric known for a conciliatory approach and backed by reformists, will have only limited say in policy determined by Iran's supreme leader; but with the Syrian carnage fuelling rage among Sunni Arabs across the region, any gestures from Tehran may help contain it.
