Trump: Iran has taken too long to negotiate - now it will have to pay the price

In a post on his Social Truth network, the American president said Iran"simply spoke and did nothing", adding: "Middle East User is dead".

Both the United States and Iran often post for the war on social media, exchanging threats, broadcasting Telegrafi.

This comes after the United States said they hit Iran in response to the collapse of an American Army helicopter last night, with Iran taking revenge on US bases in Bahrain, Jordan and Kuwait.

It's not clear whether the American president's post signals a change in negotiations or not.

He has often threatened Iran in social media, saying once: "An entire civilization will die tonight".
