The Trump administration said Friday it is sending more troops, fighter jets and missile defense weaponry to Saudi Arabia to help bolster the kingdom’s defenses after a September attack on its oil facilities.

Defense Secretary Mark Esper ordered the deployment of 3,000 service members, two fighter squadrons, one air expeditionary wing, two Patriot Missile batteries and one THAAD missile defense system, Pentagon spokesperson Jonathan Hoffman said.

The United States, European governments and Saudi Arabia blamed Iran for the September attack on Saudi oil facilities. Tehran has denied it was behind the drone and cruise missile assault that heavily damaged key oil sites.

"As we have stated, the United States does not seek conflict with the Iranian regime, but we will retain a robust military capability in the region that is ready to respond to any crisis and will defend U.S. forces and interest in the region," Hoffman said.
