Tehran:Iranian officials have warned the US against any attempt to block the fuel delivery by Iranian tankers to Venezuela.
Foreign minister Mohammad Javad Zarif said in a letter to UN Secretary-General Antonio Guterres on Sunday that the illegal, dangerous and provocative US threats against the Iranian tankers were a form of piracy and a big threat to international peace and security, reports Xinhua news agency.
"The US must stop acting like a bully at the international level and respect the rule of international laws, in particular the right to free shipping in free waters," he said in his letter.
Zarif noted that the US administration would be responsible for the consequences of any illegal move.
