Ali Abdullahi, commander of Iran's Khatam al-Anbiya Central Headquarters, warned Saturday that any country serving as a defensive shield for the United States would be drawn into the war.
"Any country that places itself as a defensive shield for criminal and aggressor America will burn in the fires of war," Abdullahi said, according to Iranian media.
Abdullahi, whose command oversees Iranian military operations in the war, said the United States was pursuing what he called a policy of warmongering that would escalate the regional conflict.
"The U.S. is pursuing a policy of warmongering that will escalate the regional war," he said.
He described Washington's policy as a dangerous consequence of what he called a U.S. strategy to establish illegitimate dominance in the region.
Abdullahi said the U.S. attack on Iran on Feb. 28 showed that Washington would not refrain from what he described as destructive attacks targeting the interests and resources of Muslims to achieve its "satanic" goals.
He also warned countries in the region, claiming that the United States was using their wealth and infrastructure as a shield for its "rotten army" and to ensure Israel's security.
Abdullahi said Washington was trying to impose the cost of the war on regional countries.
He urged countries in the region to review their cooperation with the United States, warning that those serving as a "shield" for Washington would also be harmed by the war.
Muslim countries must monitor what he called America's crimes with foresight and reconsider their cooperation and alliance with Washington, Abdullahi said.
Meanwhile, the U.S. Embassy in Amman warned Saturday that U.S. citizens in Jordan should stay away from military bases in the country because of rising tensions in the Middle East.
In a statement published on its website, the embassy said the security situation in the Middle East remains "complex and volatile" and that unexpected developments may occur.
The statement said travel in the region could be disrupted, flights could be canceled and airspace could be closed periodically.
It advised U.S. citizens in the region to consider leaving the country or be prepared to do so if the security situation deteriorates.
The embassy called on U.S. citizens to follow security alerts and instructions issued by Jordanian authorities and to stay away from demonstrations, large crowds and areas with a heavy security presence.
The statement said there was a risk of attacks targeting U.S. interests, including U.S. diplomatic missions.
It also warned that Iran and allied groups could target U.S. interests, U.S.-linked locations and citizens around the world.
