The U.S. State Department condemned the alleged Iranian attempt and the UN Secretary-General Antonio Guterres called for "maximum restraint."

We will continue to work closely with the United Kingdom and our allies to ensure the Iranian regime's malign activities do not further disrupt international law, maritime security or global commerce."
The latest incident comes amid rising concerns after Iran breached the 2015 nuclear deal exceeding the stockpile of enriched uranium regulated under the deal.
