Iran to work on nuclear-powered boats after US 'violation' of deal
Iran's President Hassan Rouhani ordered scientists on Tuesday to start developing systems for nuclear-powered boats in reaction to what he called the United States' violation of a global atomic deal.
The announcement marked Iran's first concrete response to a US Congress decision last month to extend legislation making it easier for Washington to reimpose sanctions on Tehran.
Rouhani described the technology as a "nuclear propeller to be used in marine transportation", but did not say whether that meant just ships or possibly also submarines. Iran said in 2012 that it was working on its first nuclear-powered submarine.
His words will stoke tensions with Washington, already heightened by comments from US president-elect Donald Trump who has vowed to scrap the deal under which Iran agreed to curb its nuclear activities in exchange for lifted sanctions.
There was no immediate reaction from the Vienna-based International Atomic Energy Agency (IAEA), which monitors Iran's nuclear work.
"With regards to recent [US Congress] legislation to extend the Iran Sanctions Act, I order the Atomic Energy Organisation of Iran to... plan the design and construction of a nuclear propeller to be used in marine transportation," Rouhani wrote in a letter published by state news agency IRNA.
US Congress members have said the extension of the bill does not violate the nuclear deal agreed last year to assuage Western fears that Iran is working to develop a nuclear bomb.
The act, Congress added, only gave Washington the power to reimpose sanctions on Iran if it violated the pact.
Washington says it has lifted all the sanctions it needs to remove under the deal between major powers and Iran.
But Iran's Supreme Leader Ayatollah Ali Khamenei said last month that the extension was a definite breach and Iran would "definitely react to it".
Iran has always argued its nuclear programme was for peaceful purposes.
