A White House decision to dispatch an aircraft carrier and other military resources to send a message to Iran followed "clear indications" that Iranian and Iranian proxy forces were preparing to possibly attack U.S. forces in the region, a defense official told the Associated Press.
The official, who spoke on condition of anonymity to discuss sensitive information, said the Pentagon approved the deployments and that U.S. forces at sea and on land were thought to be the potential targets. The official declined to be more specific.
White House national security adviser John Bolton said in a statement Sunday night that the U.S. is deploying the USS Abraham Lincoln Carrier Strike Group and a bomber task force to the U.S. Central Command region, an area that includes the Middle East.
Bolton said the move was in response to "a number of troubling and escalatory indications and warnings." He didn't provide details, but said the U.S. wants to send a message that "unrelenting force" will meet any attack on U.S. interests or those of its allies.
"The United States is not seeking war with the Iranian regime, but we are fully prepared to respond to any attack, whether by proxy, the Islamic Revolutionary Guard Corps, or regular Iranian forces," he said.
The Pentagon had no immediate comment on the Bolton statement.
The Abraham Lincoln and its strike group of ships and combat aircraft have been operating in the Mediterranean Sea recently. Last Wednesday a group of senior Albanian government officials visited aboard the Lincoln as it sailed in the Adriatic.
Bolton's reference to the Central Command area would mean the Lincoln is headed east to the Red Sea and perhaps then to the Arabian Sea or the Persian Gulf. The U.S. Navy currently has no aircraft carrier in the Persian Gulf.
Bolton's mention of deploying a bomber task force suggests the Pentagon is deploying land-based bomber aircraft somewhere in the region, perhaps on the Arabian Peninsula.
The Trump administration has been intensifying a pressure campaign against Iran.
Last month, President Donald Trump announced the U.S. will no longer exempt any countries from U.S. sanctions if they continue to buy Iranian oil, a decision that primarily affects the five remaining major importers: China and India and U.S. treaty allies Japan, South Korea and Turkey.
The U.S. also recently designated Iran's Revolutionary Guard as a terrorist group, the first ever for an entire division of another government.
Trump withdrew from the Obama administration's landmark nuclear deal with Iran in May 2018 and, in the months that followed, reimposed punishing sanctions including those targeting Iran's oil, shipping and banking sectors.
Bolton and Secretary of State Mike Pompeo have in recent months spoken stridently about Iran and its "malign activities" in the region.
