Trump warns Iran, but doesn't rule out lifting sanctions

President Donald Trump on Wednesday warned Iran against further uranium enrichment but left open the possibility the US could lift sanctions to pave the way to a meeting with President Hassan Rouhani.

Asked if he would ease crippling sanctions to help bring about a meeting with the Iranian leader, Trump replied "we will see what happens," while warning it would be "very, very dangerous" for Iran to boost its enriched uranium stockpiles.
