Iran's Revolutionary Guard Corps said on Friday they targeted a US early-warning radar in Bahrain, the first such claim of an attack on American military assets in a Gulf country since early September.
The IRGC said the strike was in retaliation for what they described as an air attack on a telecommunications tower in Iran's southern Sirik county, in Hormozgan province, according to Iranian state media.
The claim came amid a fragile lull in the conflict between Iran and the US, which began with US and Israeli strikes on Iran on February 28 and has since spread across the region.
Iran launched missile and drone attacks on US bases in Gulf states and sought to restrict shipping through the Strait of Hormuz, a vital route for global oil and gas supplies. Washington, in turn, imposed a naval blockade on Iranian ports.
There was no immediate comment from the US or Bahrain.
Trump warns he could renew strikes on Iran 'without hesitation'
US President Donald Trump threatened Thursday to renew military strikes against Iran in an interview with the Salem News Channel.
When asked whether he would hesitate to use military force to prevent Iran from threatening US allies and American vessels, he replied, "No, without hesitation."
Trump added that the Iranian regime is on the brink of collapse, and claimed that inflation in the country has reached 301%, its economy has been destroyed, and its military forces have been wiped out.
