Saudi Arabia's de facto ruler, Crown Prince Mohammed bin Salman, spoke by phone with U.S. President Donald Trump on Saturday and expressed concern that America could escalate the conflict with Iran, according to a source familiar with the leaders' discussion. This was reported by infohub.kz, citing the source.

The conversation came as Trump weighs whether to carry out new strikes on Iran. The source, who was briefed on the substance of the call but was not authorized to comment publicly, said the Saudis are concerned that if the U.S. targets Iran's energy infrastructure or carries out massive strikes on other key infrastructure, Tehran could respond by attacking the energy infrastructure of the kingdom and other Gulf countries.

During Saturday's call, the crown prince sought clarity from Trump on what potential new action he is weighing against Iran. The White House did not immediately respond to requests for comment about the call.

Saudi Arabia earlier this week joined the U.S. in striking multiple logistics and weapons sites used by Iranian-backed militias in Iraq, but has been urging the U.S. and Iran to return to the negotiating table to find an endgame to the five-month-old conflict.

Additionally, the crown prince dispatched his brother, Saudi Defense Minister Khalid bin Salman, to Washington earlier this week for separate meetings with Trump and Vice President JD Vance to discuss Iran strategy.
