Iran's Islamic Revolutionary Guard Corps (IRGC) have come out to say that they will be "determined to respond to any threat at the same level as it creates in terms of deterrence". Adding that if the US decides to "hit electricity, then we will hit electricity". And if the US plans attacks on power plants, then Iran will respond by striking Israel's power plants and regional facilities that supply electricity to US bases.
This of course is a response to US president Trump's warning over the weekend. Trump delivered a 48-hour ultimatum to Iran on Saturday, calling for the reopening of the Strait of Hormuz. And if not, he will order the US military to "hit and obliterate" Iran's power plants - starting with "the biggest one first".
He didn't specifically name it but it likely points to the Bushehr nuclear power plant, which had already been partially damaged last week. That or the Damavand power station (natural gas plant) close to Tehran. Or perhaps he will call the order to strike both targets. So, we'll see.
With Trump delivering that ultimatum on Saturday, the 48-hour clock will run out at the end of today. As such, we can only wait and see if he will walk the walk after talking the talk.
Iran had also warned over the weekend that they could continue to target other key infrastructure across the Gulf region, such as water desalination facilities. That is something that they already began outlining last week already here. That was after the South Pars gas field was attacked of course.
