Saudi foreign minister says has invited Iran's Zarif to visit

 Saudi Arabia has invited Iran's foreign minister to visit, Riyadh said on Tuesday, hinting at the possibility of a thaw between two bitter rivals, whose struggle for influence is evident in conflicts throughout the region.
Iranian President Hassan Rouhani has adopted a conciliatory tone towards Tehran's neighbors since taking office last year, but while Foreign Minister Mohammad Javad Zarif has visited other Gulf Arab states, he has not yet been to Saudi Arabia.
Rapprochement between the two countries would have ramifications across the Middle East, potentially cooling political and military struggles in Syria, Iraq, Lebanon, Bahrain and Yemen.
