Riyadh accuses Tehran of fomenting trouble in Bahrain and even Saudi Arabia itself, Reuters reported

“It’s a lie that Satan’s representative, Khamenei, mourns the Mina incident victims,” Saudi prince Khaled Al Saud tweeted, referring to Iran’s Supreme Leader Ali Khamenei.
“His dirty hands are stained with the blood of the children of Syria and the Sunnis of Iraq,” the prince told his nearly quarter of a million followers.
Saudi Foreign Minister Adel al-Jubeir, a longtime adviser to the kingdom’s rulers, wearily accused Tehran of playing politics. “We will reveal the facts when they emerge, and we will not hold anything back,” he said.
A 1996 truck-bombing in the kingdom that killed 19 U.S. service personnel and clashes at the 1987 haj between Iranian protesters and Saudi police that led to the death of 400 people, mainly Iranians.
Saudi Arabia and the United States accused Iran of orchestrating the 1996 attack.
Not only are the two competitors openly tussling for influence in Arab countries, but Saudi Arabia is worried that Washington has realigned with Tehran at Arab expense by backing a deal settling Iran’s long-standing nuclear dispute.
Alive to what he sees as a U.S.-Iran detente, Saudi Arabia’s new monarch, King Salman, is pushing for Sunni Muslim Middle East countries to set aside differences over political Islam and focus on what it sees as the more urgent threat from Tehran.
The diplomatic heft that Riyadh employs in such efforts is rooted in its prestigious role as custodian of Islam’s holiest places.
