Trump tells Iran 'be careful' after Tehran vows to boost uranium enrichment

U.S. President Donald Trump said on Sunday that Iran "better be careful". It came hours after Tehran announced it would shortly boost its uranium enrichment above a cap set by a landmark 2015 nuclear deal.

U.S. PRESIDENT, DONALD TRUMP said "Iran better be careful, because you enrich for one reason and I won't tell you what the reason is, but it's no good. They better be careful."

In a sign of heightening tensions, France, Germany and Britain expressed concerns over the step taken by Tehran, its latest effort to force the West to lift sanctions ravaging its limping economy. Iran has denied any intent to develop nuclear weapons.
