Saudi Foreign Minister Prince Saud al-Faisal discussed Tuesday regional developments and the fight against Islamic State jihadists with a senior Iranian official visiting his country's longtime regional rival, an Iranian diplomat said. The visit by Iran's Deputy Foreign Minister Hossein Amir-Abdollahian to the city of Jeddah was the first by a high-level official from Shiite Iran to Sunni Saudi Arabia since Hassan Rouhani became the Islamic republic's president in August last year. The meeting was "fruitful", Iran's representative at the Jeddah-based Organisation of Islamic Cooperation (OIC) Riza Hamid Dahqani told AFP.
