President Trump lobbed a strong warning to Iran on Sunday after the rogue nation announced it had ratcheted up its uranium enrichment beyond the limit allowed by the 2015 nuclear deal with world powers.

“Iran better be careful. … Iran is doing a lot of bad things,” Trump said. “Iran will never have a nuclear weapon.”

Iran has said it was inching its program closer toward weapons-grade levels, while calling for a diplomatic solution to a crisis that has raised tensions with the U.S.

“Iran’s latest expansion of its nuclear program will lead to further isolation and sanctions. Nations should restore the longstanding standard of no enrichment for Iran’s nuclear program. Iran’s regime, armed with nuclear weapons, would pose an even greater danger to the world,” Secretary of State Mike Pompeo tweeted.
