Washington: A senior Pentagon official said on Wednesday there were indications that Iran could potentially carry out aggressive actions in the future, amid simmering tensions between Tehran and Washington.
Tensions in the Gulf have risen since attacks on oil tankers during the summer, including off the coast of the United Arab Emirates, and a major assault on energy facilities in Saudi Arabia. The United States has blamed Iran.
"We also continue to see indications, and for obvious reasons I won't go into the details, that potential Iranian aggression could occur," John Rood, the Pentagon’s No. 3 official, told reporters.
Rood did not provide details about what information he was basing that on or any timeline.
"We've sent very clear and blunt signals to the Iranian government about the potential consequences of aggression," Rood said.
Two US officials, speaking on the condition of anonymity, said there was intelligence over the past month indicating that Iran was moving forces and weapons in the region.
It was not clear what specifically Iran was looking to do with the movements, they added.
One of the officials said that part of the concern was Iranian activity inside Iraq, which is experiencing anti-government protests.
Last year, Reuters reported that Iran had given ballistic missiles to Shi’ite proxies in Iraq and was developing the capacity to build more there to deter attacks on its interests in the Middle East and to give it the means to hit regional foes.
The United States has deployed thousands of additional military forces in the Middle East, including bombers and air defence personnel, to act as a deterrent against what Washington says is provocative Iranian behavior.
The US officials said there were ongoing discussions about adding more US troops in the region but that no decision had been made and the situation was fluid. They said the military regularly talked about forces around the world, including in the Middle East.
Iran has been facing weeks of sometimes violent protests against gasoline price hikes.
The unrest, which began on November 15 after the government abruptly raised fuel prices by as much as 300 per cent, spread to more than 100 cities and towns and turned political as young and working-class protesters demanded clerical leaders step down.
Tehran's clerical rulers have blamed "thugs" linked to its opponents in exile and the country’s main foreign foes for the unrest.
