美国战机在伊朗当地时间星期日发动的袭击中轰炸了伊朗的三处铀浓缩设施。唐纳德·特朗普总统说，这次袭击“摧毁”了这些设施，并阻止了伊朗制造核武器。他说伊朗距离能够建造核武器只有几个星期的时间。
在星期四的新闻发布会上，白宫新闻秘书卡罗琳·莱维特(Karoline Leavitt)说： “我们要确保能够达成伊朗同意不进行核浓缩的民用核项目的局面。”

Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
