The United States said Monday it has approved the deployment of 1,000 additional troops to the Middle East, against the backdrop of soaring tensions with Iran.
Acting Defense Secretary Patrick Shanahan said in a statement that the troops were being sent "for defensive purposes to address air, naval, and ground-based threats in the Middle East."
The US has blamed Iran for last week's attacks on two tankers in the Gulf of Oman, a charge Tehran has denied as "baseless."
"The United States does not seek conflict with Iran," the statement said, adding that the deployment aimed "to ensure the safety and welfare of our military personnel working throughout the region and to protect our national interests."
