On Monday, U.S. President Donald Trump threatened Iran with “great force” if it attacked U.S. interests in the Middle East. Washington suspects that militia with ties to Iran organized a rocket attack in Iraq’s capital Baghdad.

On Tuesday, Iran said it would resist U.S. pressure, declining further talks under current circumstances.
