The US has deployed an aircraft carrier to the Middle East to send a "clear and unmistakable message" to Iran, ONA reports citing BBC.
John Bolton, US national security advisor, said they were acting "in response to a number of troubling and escalatory indications and warnings".
The deployment of the warship was based on claims of a possible attack on US forces, Reuters news agency reports, quoting an unnamed US official.
Mr Bolton added that they would counter any attack with "unrelenting force".
In a statement, Mr Bolton said: "The United States is deploying the USS Abraham Lincoln Carrier Strike Group and a bomber task force to the US Central Command region to send a clear and unmistakeable message to the Iranian regime that any attack on United States interests or on those of our allies will be met with unrelenting force."
