Saudi king slams Iran as 'spearhead of global terrorism'

RIYADH: Saudi Arabia's King Salman on Sunday accused regional rival 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 US 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.

The Saudi leader's speech came minutes before a highly anticipated address by Trump, who arrived in the kingdom on Saturday on his first foreign tour since taking office.

The United States 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".
