Iran ramps up uranium enrichment and seizes tanker

Iran currently enriches its uranium stockpile up to around 4.5%, which is above the 3.67% cap imposed by the 2015 pact with world powers, but far short of the 90% that is considered weapons-grade. Iran has continually denied it intends to assemble nuclear weapons.

The country had informed the International Atomic Energy Agency (IAEA) of its intent to enrich uranium at 20%, IAEA spokesman Fredrik Dahl told CNN on Friday. On Monday morning, government spokesman Ali Rabiei said it started the enrichment process a "couple of hours ago" in the Fordow site, noting that the first UF6 enriched uranium would be produced in a few hours, IRNA said.

The US State Department condemned both the tanker seizure and Iran's resumption of uranium enrichment, with a spokesperson noting that "Iran's enrichment program was originally developed in secret, including at Fordow, and Iran retained a vast archive of records from its past nuclear weapons program, along with many of the key personnel who led that program."

"The United States and the rest of the international community will assess Iran's actions in light of this provocative history," the spokesperson said.

 

A challenge from Iran

 

The development poses a challenge for US President-elect Joe Biden, who has pledged to reinstate the deal after he takes office on January 20. President Trump walked away from the agreement in 2018, instead restarting sanctions on the Iranian regime.

The ramp-up came after Iran's parliament passed a law last month to boost uranium enrichment to pre-2015 levels and block nuclear inspections if sanctions are not lifted. The bill was approved in the wake of the assassination of Iran's chief nuclear scientist Mohsen Fakhrizadeh in November.

"The law obliges the Atomic Energy Organization of Iran to produce at least 120 kg of 20% enriched uranium annually and store it inside the country," the Mehr news agency reported.

Iranian president Hassan Rouhani said in January 2020 that Iran was enriching more uranium than before the deal was signed, and in March the United Nations found that the country had nearly tripled its stockpile in a matter of months.

Rouhani, whose government signed the 2015 deal with the US and other world powers, opposed last month's bill, arguing that it would undermine diplomacy.

Iran's government has repeatedly called on the US to restore the agreement that Trump withdrew from in 2018.

Biden's national security adviser Jake Sullivan told CNN on Sunday that the incoming US administration would reenter the pact if Iran came back into compliance with it.

Sullivan also said the Biden administration would then seek a "follow-on negotiation" over Iran's ballistic missile capabilities.

"Our view is that ballistic missiles, and Iran's ballistic missile program, has to be on the table as part of that follow-on negotiation," Sullivan said, adding the Biden administration would seek to bring some of Iran's regional partners to the table.

Rouhani said last month that Iran's missile program was non-negotiable, Reuters reported.

 

Tanker seized

Meanwhile Monday, news agencies and the Dryad Global firm reported that Iran had seized a chemical tanker bearing the South Korean flag.

"Reporting indicates that the South Korean flagged Chemical Tanker HANKUK CHEMI (IMO:9232369) has likely been detained by Iranian forces in the Straits of Hormuz while inbound to Fujairah," Dryad Global said.

South Korea sent its Cheonghae anti-piracy unit to the Strait of Hormuz in response, its Ministry of Defense said, adding that there were 20 crew on board including five South Koreans.

A "vessel that was sailing near Oman sea of the Hormuz waters on January 4 afternoon is moving to the Iranian waters following Iranian authorities' request," the ministry said in a statement.

The ministry and the South Korean Embassy have asked Iranian authorities to confirm the safety of the crew and to release the vessel as soon as possible.

The United Kingdom Maritime Trade Operations (UKMTO), which is part of Britain's Royal Navy, said an "interaction occurred" within the Strait of Hormuz between a merchant vessel and Iranian authorities, pushing the vessel to make "an alteration of course into Iranian territorial waters."

Iran said the vessel was seized for "creating environmental and chemical pollution in the Persian Gulf," semi-official news agency Tasnim said. The vessel has been seized by the navy of the Islamic Revolutionary Guard Corps, according to the Mehr news agency.

CNN has reached out to the South Korean government for a comment.

 

US to keep aircraft carrier in the region

 

Acting US Secretary of Defense Christopher Miller ordered the USS Nimitz to return to the Middle East following a White House meeting Sunday, a senior defense official told CNN.

The decision reversed Miller's order last week to send the aircraft carrier out of the region and home, in part, to send a de-escalation signal to Iran amid rising tensions between Washington and Tehran.

One defense official says Miller's idea of de-escalation had not been adopted as a formal, approved policy. It took top commanders by surprise, several defense sources said. US Central Command wanted the carrier to stay in the region because of the policy of Iran deterrence.

The White House and NSC did not immediately respond to CNN's request for comment on Monday.

On Sunday, Miller announced that the USS Nimitz would remain in place due to purported Iranian threats "against President Trump and other US government officials." Miller said in a statement that he had "ordered the USS Nimitz to halt its routine redeployment." The carrier will now "remain on station in the US Central Command area of operations," Miller added.

"No one should doubt the resolve of the United States of America," he said.
