Tehran, Iran - Iran's Revolutionary Guards said their forces had targeted a US early warning radar system in Bahrain, according to a statement carried by the Iranian state broadcaster on Friday.
There was no immediate confirmation of a strike on Bahrain by Manama or the US, whose bases and equipment in the Gulf were repeatedly targeted earlier in its eight-month war with Iran.
"A few hours ago, IRGC Aerospace Force fighters targeted and destroyed the U.S. aggressors' early-warning radar on the island of Bahrain in response to the enemy's air aggression against a telecommunications tower in Sirik," the Guards said in the statement, referring to a port city in southern Iran.
"This is a serious warning to the aggressor enemy to stop its aerial provocations and oil smuggling in the Strait of Hormuz," it added in the statement, posted by the state broadcaster on Telegram.
The US Central Command, which oversees American military operations in the region, said last month that it had helped Gulf countries export 1.5 billion barrels of oil since the summer via Hormuz, a key energy trading route.
The US and Israel launched attacks on Iran on February 28, triggering the war.
In retaliation, Iran restricted shipping through Hormuz and struck infrastructure including airports, seaports, energy facilities, landmarks, and American assets in the US-allied countries.
The US imposed a blockade on Iranian ports early in the war, and in August, Washington announced what it called an "economic asphyxiation" campaign on Iran aimed at curbing its trade and financial flows.
Washington has appeared to dial back threats of renewed strikes after the defeat of President Donald Trump's Republican party in recent midterm elections, in part due to the unpopularity of the war on Iran.
