Pompeo lands in Saudi for talks focused on Iran

US Secretary of State Mike Pompeo landed in Riyadh on Wednesday for talks with Saudi leaders focused on countering Tehran, his first visit since a top Iranian general's killing sent regional tensions soaring.

The top US diplomat, whose visit follows his first trip to sub-Saharan Africa, will hold talks with King Salman and his son Crown Prince Mohammed bin Salman as well as Foreign Minister Faisal bin Farhan, State Department officials said.

"We'll spend a lot of time talking about the security issues with the threat from the Islamic Republic of Iran in particular," Pompeo told reporters in the Ethiopian capital Addis Ababa before heading to Riyadh.

Pompeo said the United States was "prepared to talk anytime" to Iran but emphasised that the Iranian regime has "got to fundamentally change their behaviour".

"The pressure campaign continues. It's not just an economic pressure campaign, its diplomatic pressures, isolation through diplomacy as well," he said.
