Tehran warns Biden that if US strikes Iranian soil in retaliation for death of three soldiers the Islamist regime will hit back at American targets across the Middle East – sparking all-out war between the foes

• Tehran has told Washington, via intermediaries, that it will attack U.S. targets in the Middle East if the Pentagon launches strikes on Iranian soil
• Joe Biden on Tuesday said that he had made up his mind about how to respond to Sunday’s killing of three U.S. service members by an Iranian-backed militia
• The strikes are expected to take place over time, and in waves: targets could include Iranian naval vessels in the Persian Gulf, or a cyberattack
