Iran Says It Is Breaking Nuclear Enrichment Limits
Iran's nuclear energy agency says the country has broken limits set in its 2015 nuclear deal with world powers.
The agency reported on Monday that Iran began enriching uranium to 4.5 percent, passing the 3.67 percent limit set under the deal. The international agreement was meant to restrain the country's nuclear activities.
The higher level of uranium enrichment is the second time Iran has violated the agreement. Last week, Iran said it had produced more than 300 kilograms of low-enriched uranium and announced plans to continue making more.
Uranium enriched to 5 percent is reported to be enough to produce fuel for a nuclear energy center. However, it is far below the purity needed to make a nuclear weapon. For such weapons, a purity level of about 90 percent is required.
In recent weeks, Iran said several times that it would surpass limits set by the Joint Comprehensive Plan of Action. Iran's government is trying to pressure other countries, especially those in Europe which signed the agreement, to do more to help Iran economically.
The United States, China and Russia also signed the 2015 Iran nuclear deal.
Iranian President Hassan Rouhani said last week that Iran was prepared to enrich "any amount that we want" beyond the 3.67 level. He also announced that Iran would restart construction at the Arak heavy water reactor. That nuclear center was closed as part of the 2015 nuclear deal.
A spokesman for Iran's nuclear agency suggested that Iran may consider enriching uranium to 20 percent. The Associated Press reported his comments.
The official also suggested that Iran might add to its current number of centrifuges -- the devices used to increase the purity of uranium.
US president again warns Iran
U.S. President Donald Trump warned Iran on Sunday to "be careful" about its activities.
Trump spoke soon after Secretary of State Mike Pompeo wrote that: "Nations should restore the longstanding standard of no enrichment for Iran's nuclear program." Pompeo's comments appeared on the social networking service Twitter. He went on to say that, if Iran had nuclear weapons, it would be an even bigger threat to the world.
The United States withdrew from the nuclear deal with Iran last year. At the time, Trump said that the deal was doing little to stop Iran from developing nuclear weapons. The Trump administration then placed additional restrictions on Iran.
France, Britain and Germany have been trying to save the deal by creating a system by which Iran can carry out limited trade. However, Iran's recent activities make even that attempt unlikely to succeed.
Earlier this month, an Iranian oil tanker carrying over 2 million barrels of oil was seized in waters near the British port of Gibraltar. Reports say the oil was meant to go to Syria, which is under European Union sanctions.

They have also placed restrictions on buying homes and cars, with stricter rules for people without a city hukou.
The shortage of resource has placed a big restriction on economic development.
周一，该机构报告称，伊朗开始将铀浓缩水平提升至4.5%，超过了核协议规定的3.67%的上限 。这项国际协议旨在限制伊朗的核活动 。
这次更高级别的铀浓缩破禁是伊朗第二次违反核协议 。上周，伊朗表示已经生产了300多公斤低浓缩铀，还宣布将继续生产更多 。
据报道，浓缩铀水平达到5%足以为一个核能中心生产燃料 。然而，这远远低于制造核武器所需的纯度 。制造核武器的纯度需达到90%左右 。
最近几周，伊朗多次表示，将突破《联合全面行动计划》（伊核协议）设定的限制 。伊朗政府正试图向其他国家施压，尤其是签署协议的欧洲国家，要求它们在经济上为伊朗提供更多帮助 。
伊朗总统哈桑·鲁哈尼(Hassan Rouhani)上周表示，伊朗准备超过3.67%上限，浓缩到“我们想要的任何数量” 。他还宣布，伊朗将重启阿拉克重水反应堆的建设 。作为2015年核协议的一部分，该核中心被关闭 。
伊朗原子能机构发言人表示，伊朗可能考虑将铀浓缩水平提升至20% 。美联社报道了他的评论 。
特朗普发表该言论前不久，美国国务卿蓬佩奥写道：“各国应该恢复伊朗核计划不进行浓缩的长期标准 。”蓬佩奥这一评论发表在社交网站推特上 。他接着称，如果伊朗拥有核武器，将对世界构成更大的威胁 。”
美国去年退出了与伊朗的核协议 。当时，特朗普表示，该协议对阻止伊朗发展核武器几乎没有作用 。特朗普政府随后对伊朗施加了更多限制 。
法国、英国和德国一直试图通过建立一套体系，供伊朗进行有限贸易，以此挽救该协议 。然而，伊朗最近的活动表明，即便是如此的尝试，成功的机会也很渺茫 。
本月早些时候，一艘载有200多万桶石油的伊朗油轮在英国直布罗陀港附近海域被扣留 。有报道称，这些石油原本是要运往叙利亚的，而叙利亚正受到欧盟的制裁 。
