Iranian Foreign Minister Mohammad Javad Zarif said on Saturday that the U.S. decision to deploy more troops to the Middle East in response to the perceived threat from Iran was "extremely dangerous" for peace.
The United States said it was sending 1,500 troops to region in what it called an effort to bolster defenses against Tehran, and it accused Iran's Revolutionary Guards of direct responsibility for attacks on tankers this month.
"The Americans have made such allegations to justify their hostile policies and to raise tensions in the Persian Gulf," Zarif told state news agency IRNA.
"Increased U.S. presence in our region is extremely dangerous and it threatens international peace and security, and this should be addressed," he said.
U.S. President Donald Trump also invoked the threat from Iran to declare a national security-related emergency that would clear the sale of billions of dollars’ worth of weapons to Saudi Arabia, the United Arab Emirates and other countries without congressional approval.
It follows decisions to speed up the deployment of an aircraft carrier strike group as well as to send bombers and additional Patriot missiles to the Middle East.
Following U.S. media reports that Zarif had met Senator Dianne Feinstein during a U.S. visit last month, Iran's Foreign Ministry said informative talks were common and did not involve negotiations.
Separately, a Revolutionary Guards commander said the security of the Strait of Hormuz, a key oil shipping route, was linked to Iran being able to export its oil, the semi-official news agency Fars reported.
"Major General Gholamali Rashid said that talking about security and stability in the Persian Gulf and the Strait of Hormuz is not possible without considering the interests of the Iranian nation, including the export of oil," Fars said.
Iran has threatened to disrupt oil shipments through the Strait of Hormuz if the United States tries to strangle Tehran's economy by halting its oil exports through increased sanctions.
