Iran has sharply increased its stockpile of a critical raw material for atomic weapons, according to a confidential U.N. report.

Iran's stock of uranium close to weapons grade has jumped since December, two reports by the U.N. nuclear watchdog said on Wednesday.

The report by the Vienna-based International Atomic Energy Agency said that as of Feb. 8, Iran has 605.8 pounds of uranium enriched up to 60%.

President Donald Trump issued a warning to Iran in a Thursday letter, telling Tehran it can either "make a deal" regarding its nuclear program or face off with the U.S. "militarily."

The report from the International Atomic Energy Agency comes amid growing concerns that Iran may pursue a nuclear weapon.

"There are two ways Iran can be handled, militarily or you make a deal. I would prefer to make a deal," Trump told Fox host Maria Bartiromo.

Iran's Supreme Leader Ayatollah Ali Khamenei firmly rejected U.S. President Donald Trump's negotiation attempts over a nuclear deal, citing undue pressure. Despite openness to dialogue, Trump's 'maximum pressure' has intensified,

Iran’s stockpile of uranium enriched just below the level needed for nuclear weapons surged more than 50% in the last three months, defying mounting pressure on the Islamic Republic to curb its atomic activities.

The EU emphasized that Iran has significantly deviated from its commitments under the Joint Comprehensive Plan of Action (JCPOA) and has gained irreversible nuclear knowledge.
