Saudi Arabia's King Salman on Sunday (May 21st) accused regional rival Iran of exporting extremist Islamic movements to the world and vowed to eliminate the "Islamic State of Iraq and Syria" (ISIS), AFP reported.
"The Iranian regime has been the spearhead of global terrorism since the Khomeini revolution" in 1979, King Salman said in a speech to leaders.
Saudi Arabia was also determined to "eliminate" ISIS, the king said.
The US and Saudi Arabia on Saturday announced an arms deal worth almost $110 billion, described as the largest in US history.
US Secretary of State Rex Tillerson said the deal was aimed at countering "malign Iranian influence".
