The Pentagon is expected to send thousands of members of the 82nd Airborne Division, an elite unit of the US Army, to the Middle East as part of a large-scale military buildup in the region.
The move comes as President Donald Trump continues to hint at a possible settlement through a deal with Iran.
The planned deployment is an extension of the previous US administration's consideration of increasing the military presence in the region, including the potential for broader operations into Iranian territory.
The development raises the risk of an escalating conflict, now in its fourth week and having a significant impact on global markets.
The troops involved are reportedly based at Fort Bragg, but the exact location of their deployment in the Middle East and the timeline for their arrival were not disclosed. The US military referred questions to the White House, which stressed that any official announcement regarding the deployment would be made by the Pentagon.
A White House spokesman also stressed that all military options remain open to the President.
While no decision has been made to send troops directly into Iran, the deployment is seen as an effort to build operational capabilities for possible future actions in the region.
Estimates suggest that between 3,000 and 4,000 personnel will be involved in the surge.
The move follows an earlier decision to send thousands of Marines and sailors aboard the USS Boxer with a Marine Expeditionary Unit and escort ships to the Middle East.
Before the surge, about 50,000 US troops were deployed to the region, indicating the scale of the growing military presence.
The development comes amid diplomatic uncertainty as Donald Trump has previously called off a threat to attack Iranian facilities and said productive talks were taking place.
However, Iran has denied any such talks, adding to the narrative tension between the two sides.
Since the military operation by the US and Israel began on February 28, about 9,000 targets inside Iran have been struck.
The conflict has also killed 13 US service members so far, with another 290 wounded, most of whom have returned to duty, although some remain in critical condition.
These overall developments reflect a significant increase in military tensions in the Middle East, with the risk of a wider conflict that could have a major impact on regional stability and the global economy.
