Iran has escalated tensions in the Middle East by declaring commercial shipping and maritime infrastructure as potential legitimate targets in the event of a US military attack on Tehran.
In a strongly worded address to parliament on Sunday, Iran's parliament speaker Mohammad Bagher Ghalibaf directly warned US President Donald Trump that any American military action would trigger a broad response.
We do not limit ourselves to responding only after an action. In the event of a US military attack, both the occupied territories and US military and shipping centres will be legitimate targets for us, Ghalibaf said.
