Pompeo and Saudi King Salman discussed regional security issues related to Iran in Riyadh on Thursday. Pompeo also met with Saudi crown Prince Mohammed bin Salman.
Tensions in the region increased significantly last month after a high-ranking Iranian military officer was killed in a US-led special operation at Baghdad airport.
Saudi Arabia, a US ally, has supported US efforts to confront Iran but warned Washington against fighting after several attacks last year damaged the Kingdom’s oil industry facilities. Saudi Arabia has accused Iran of carrying out the attacks, which Tehran denies.
The risk of a regional war decreased last month after the US and Iran refused to escalate further. After the death of General Qasem Suleimani, Iran responded with a missile attack on military bases in Iraq where American soldiers are stationed, injuring more than 100 soldiers.
Before traveling to Oman and Saudi Arabia, Pompeo spent three days in Africa, visiting the leaders of Senegal, Angola, and Ethiopia.
