Iran enriching uranium with third cascade of advanced IR-2M centrifuges: IAEA

  • The new enrichment further breaches Iran’s 2015 deal with major powers

VIENNA:  Iran has started enriching uranium with a third set of advanced IR-2m centrifuges at its underground plant at Natanz, the U.N. nuclear watchdog told its member states on Monday, a further breach of Tehran's 2015 deal with major powers.

The move is part of a recent acceleration by Iran of its violations of restrictions under that deal, which granted Iran relief from financial sanctions in return for curbs to its nuclear activities.

It began breaching limits after then-U.S. President Donald Trump quit the deal and re-imposed sanctions in 2018.

The acceleration of breaches appears aimed at raising pressure on Trump's successor Joe Biden. The new U.S. president wants to revive the accord, but Washington and Tehran are locked in a standoff over which side should move first.

The deal allows Iran to enrich uranium only with first-generation IR-1 centrifuges at the underground, commercial scale Fuel Enrichment Plant (FEP) at Natanz. In November Iran started enriching there with a first set of IR-2m machines, which are far more efficient, and has since been adding to it.

“On 7 March 2021, the Agency verified at FEP that: Iran had begun feeding natural UF6 into the third cascade of 174 IR-2m centrifuges,” the International Atomic Energy Agency said in a report obtained by Reuters, referring to uranium hexafluoride, the form in which uranium is fed into centrifuges to purify it.

“The fourth cascade of 174 IR-2m centrifuges was installed but had yet to be fed with natural UF6; installation of a fifth cascade of IR-2m centrifuges was ongoing; and installation of a sixth cascade of IR-2m centrifuges had yet to begin,” it added.

In addition to its IR-1 machines, Iran is now using 522 IR-2m centrifuges to enrich uranium to up to 5% fissile purity at the FEP, the IAEA added.

That is more than the 3.67% purity allowed under the deal but less than the 20% it is enriching to at another facility, Fordow. Uranium enriched to 90% purity can be used to make an atomic weapon.


Tunisia’s famed blue-and-white village threatened after record rains

Tunisia’s famed blue-and-white village threatened after record rains

  • The one-time home of French philosopher Michel Foucault and writer Andre Gide, the village is protected under Tunisian preservation law, pending a UNESCO decision on its bid for World Heritage status

SIDI BOU SAID, Tunisia: Perched on a hill overlooking Carthage, Tunisia’s famed blue-and-white village of Sidi Bou Said now faces the threat of landslides, after record rainfall tore through parts of its slopes.
Last week, Tunisia saw its heaviest downpour in more than 70 years. The storm killed at least five people, with others still missing.
Narrow streets of this village north of Tunis — famed for its pink bougainvillea and studded wooden doors — were cut off by fallen trees, rocks and thick clay. Even more worryingly for residents, parts of the hillside have broken loose.
“The situation is delicate” and “requires urgent intervention,” Mounir Riabi, the regional director of civil defense in Tunis, recently told AFP.
“Some homes are threatened by imminent danger,” he said.
Authorities have banned heavy vehicles from driving into the village and ordered some businesses and institutions to close, such as the Ennejma Ezzahra museum.

- Scared -

Fifty-year-old Maya, who did not give her full name, said she was forced to leave her century-old family villa after the storm.
“Everything happened very fast,” she recalled. “I was with my mother and, suddenly, extremely violent torrents poured down.”
“I saw a mass of mud rushing toward the house, then the electricity cut off. I was really scared.”
Her Moorish-style villa sustained significant damage.
One worker on site, Said Ben Farhat, said waterlogged earth sliding from the hillside destroyed part of a kitchen wall.
“Another rainstorm and it will be a catastrophe,” he said.
Shop owners said the ban on heavy vehicles was another blow to their businesses, as they usually rely on tourist buses to bring in traffic.
When President Kais Saied visited the village on Wednesday, vendors were heard shouting: “We want to work.”
One trader, Mohamed Fedi, told AFP afterwards there were “no more customers.”
“We have closed shop,” he said, adding that the shops provide a livelihood to some 200 families.

- Highly unstable -

Beyond its famous architecture, the village also bears historical and spiritual significance.
The village was named after a 12th-century Sufi saint, Abu Said Al-Baji, who had established a religious center there. His shrine still sits atop the hill.
The one-time home of French philosopher Michel Foucault and writer Andre Gide, the village is protected under Tunisian preservation law, pending a UNESCO decision on its bid for World Heritage status.
Experts say solutions to help preserve Sidi Bou Said could include restricting new development, building more retaining walls and improving drainage to prevent runoff from accumulating.
Chokri Yaich, a geologist speaking to Tunisian radio Mosaique FM, said climate change has made protecting the hill increasingly urgent, warning of more storms like last week’s.
The hill’s clay-rich soil loses up to two thirds of its cohesion when saturated with water, making it highly unstable, Yaich explained.
He also pointed to marine erosion and the growing weight of urbanization, saying that construction had increased by about 40 percent over the past three decades.
For now, authorities have yet to announce a protection plan, leaving home and shop owners anxious, as the weather remains unpredictable.
