Ahead of his meeting on Tuesday, July 9, with the Emir of Qatar at the White House, President Donald Trump once again warned Tehran. "Iran's doing a lot of bad things," Trump told reporters, adding, "Iran better be careful."

Trump had issued similar warnings in recent days after Tehran declared that it was enriching uranium up to 4.5%., breaching the 2015 nuclear accord.
Washington withdrew from the Joint Comprehensive Plan of Action (JCPOA) or Tehran's nuclear deal with World powers in May 2018, saying it gives Iran a pathway to an atomic bomb.

Immediately after its withdrawal from the JCPOA, Washington reimposed series of sanctions on the Islamic Republic, calling the leaders of Iran to either re-negotiate the deal or suffer more.

Iran has categorically dismissed the offer.

Last month Iran downed a U.S. drone over the Persian Gulf but Trump decided not to retaliate, inviting criticism of not having a consistent approach.

Meanwhile, the U.N.'s watchdog, the International Atomic Energy Agency (IAEA) verified on Monday that Iran had indeed enriched uranium beyond the limit allowed in the JCPOA.

Under the nuclear deal, the cap for enrichment is at 3.67%, a percentage monitored by IAEA inspectors.

Furthermore, the Islamic Republic has warned that it would step by step drop its commitments stipulated in the JCPOA if its demands were not met.

In the meantime, the U.S. has criticized Iran's latest move to produce higher-grade uranium, describing it as "nuclear extortion."

Enriched uranium at the 3.67% level is enough for peaceful pursuits but is far below weapons-grade levels of 90%.
