Iran has breached the limit on its stockpile of enriched uranium set under the 2015 nuclear deal with world powers. European signaturees have attempted to stick to the deal, despite the US withdrawal last year. Washington has since impose sanctions. Here is the BBC's security correspondent Frank Gardner.

Iran is being choked off economically and so far Europe has failed to convince Iran that it can offer enough of carrot to keep it within the deal.

So Iran is starting to ratchet up the pressure. The next step is expected on July the seventh in just six day's time when Iran has hinted that it's gonna start enriching uranium beyond the 3.6 percent, which is the cap set under this accord. Why does that matter? Because it makes it that much easier to race to the point at which you could produce a nuclear bomb.

The Afghan Interior Ministry says at least three people have been killed and scores injured in a car bomb attack in the Afghan capital Kabul.

BBC新闻，大家好，我是杰瑞·施密特。

伊朗违反了2015年与世界大国签署的核协议所规定的浓缩铀储备限制。尽管美国去年退出该协议，但欧洲签约国仍意图遵守这项协议。华盛顿当局随后实施了制裁。以下是BBC安全通讯员弗兰克·加德纳的报道。

伊朗在经济上受到了限制，到目前为止，欧洲未能说服伊朗其能够提供足够的好处以继续维持核协议。所以伊朗开始加大压力。下一步措施预计将于7月7日进行，也就是6天后，伊朗暗示将开始将铀的浓缩度提高至3.6％以上，3.6%是该协议规定的上限。为什么这件事这么重要？ 因为这将会让伊朗更加轻易地达到可以生产核弹的程度。
