Tehran: Iran's supreme leader Ayatollah Ali Khamenei said Tuesday that the Islamic republic will keep rolling back its commitments under the landmark 2015 nuclear deal. "You did not carry out a single one (of your commitments), why do you want us to stick to our commitments?" Khamenei said, criticising European countries which are party to the deal.

"We have just started to decrease our commitments (in the deal) and this process will certainly continue," he said in a speech in Tehran partly aired on state television. Iran-US tensions have soared since last year when President Donald Trump withdrew the United States from the hard-won 2015 nuclear deal and reimposed sanctions on the Islamic republic. Angered that its beleaguered economy is not receiving sanctions relief it believes was promised under the deal, Iran has intensified its sensitive uranium enrichment work.
