President Donald Trump is threatening sanctions on anyone who buys Iranian oil. That warning comes after planned talks between the U.S. and Iran over Iran’s rapidly advancing nuclear program were postponed.

President Donald Trump said he would impose secondary sanctions on nations or companies buying Iranian oil, ratcheting up pressure on Tehran as nuclear talks with the US hit a snag.

Iran on Friday stated that continued US sanctions on its trade partners will not alter its policy, following President Donald Trump’s threat to penalise countries or individuals dealing in Iranian oil.
