Iran threat to quit N-treaty after US move

Dubai - Tensions between Tehran and Washington have risen since last year.

Iran said on Sunday it could quit a treaty against the spread of nuclear weapons after the United States tightens sanctions, while an Iranian general said the US Navy was interacting as before with an elite military unit blacklisted by Washington.
Tensions between Tehran and Washington have risen since the Trump administration withdrew last year from a 2015 international nuclear deal with Iran and began ratcheting up sanctions.
Earlier this month, the United States blacklisted Iran's elite Revolutionary Guards (IRGC) and demanded buyers of Iranian oil stop purchases by May or face sanctions.
"The Islamic Republic's choices are numerous, and the country's authorities are considering them ... and leaving NPT (nuclear Non-Proliferation Treaty) is one of them," state broadcaster IRIB's website quoted Foreign Minister Mohammad Javad Zarif as saying.
Iran has threatened in the past to leave the NPT, as US President Donald Trump moved to scrap the 2015 deal with world powers - the United States, Russia, China, Germany, Britain and France.
Separately, Iran's armed forces chief of staff said the IRGC - which ensures security in Gulf waters and the Strait of Hormuz for Iran - had not observed any change in the US military's behaviour towards the elite force after the blacklisting.
"US warships are obliged to respond to the IRGC on the passage of the Strait of Hormuz ... and until yesterday they have been answering IRGC questions, and we have not seen change in their procedures," Major General Mohammad Baqeri was quoted as saying on Sunday by the semi-official Fars news agency.
