Iran's top diplomat promises "proportional" response to US "state terrorism"

By threatening to target Iranian cultural sites if Tehran responds to the airstrike which killed general Qasem Soleimani, US President Donald Trump showed the international community that "he has no respect for international law and is prepared to commit war crimes -- attacking cultural sites is a war crime," Iran's top diplomat said Tuesday.

Speaking to CNN's Fred Pleitgen in Tehran, Iranian Foreign Minister Javad Zarif said that Trump's actions and statements showed "he doesn't care about international law."

The strike against Soleimani while he was in Iraq was an act of "state terrorism," Zarif added, reiterating that Tehran will mount a response.
