Saudi Arabia's King Salman on Sunday accused regional rival Shiite Iran of exporting extremist Islamic movements to the world and vowed to eliminate the Islamic State group.
"The Iranian regime has been the spearhead of global terrorism since the (Ayatollah Ruhollah) Khomeini revolution" in 1979, King Salman said in a speech to leaders including U.S. President Donald Trump.
"We did not know terrorism and extremism until the Khomeini revolution reared its head," he said.
Saudi Arabia was also determined to "eliminate the Islamic State group," the king said of the Sunni Muslim jihadist organization.
The Saudi leader's speech came minutes before a highly anticipated address by Trump, who arrived in the Sunni kingdom on Saturday on his first foreign tour since taking office.
