Iran's Revolutionary Guards told Saudi Arabia and the United Arab Emirates on Friday to respect Tehran's "red lines" or face retaliation.
Iran accuses Saudi Arabia and the UAE of funding five gunmen who attacked a military parade in Iran last Saturday and killed 25 people. Saudi Arabia and the UAE have denied any involvement.
"If you cross our red lines, we will surely cross yours. You know the storm the Iranian nation can create," the Fars news agency quoted Brigadier General Hossein Salami, deputy head of the Guards, as saying.
