俄罗斯总统弗拉基米尔·普京对邻国乌克兰的“特殊军事行动”始于2月24日，俄罗斯军队从北部的白俄罗斯和东部的俄罗斯入侵。据美国官员称，乌克兰军队进行了“顽强抵抗”。
此后，俄罗斯军队在乌克兰东部有争议的顿巴斯地区发动了全面地面进攻，占领了战略港口城市马里乌波尔，并确保了通往莫斯科吞并的克里米亚半岛的沿海走廊。

电厂的所有反应堆有史以来第一次关闭
据乌克兰国家核监管机构Energoatom报道，持续遭受炮击的Zaporizhzhia核电站的所有反应堆，在该核电站历史上首次被关闭。
根据乌克兰国家核监管机构Energoatom的说法，欧洲最大的核电站Zaporizhzhia有六个反应堆，其中两个正在运行。Energoatom表示，当地时间下午12点12分，由于该地区的敌对行动，向该工厂提供电力的最后一条运行线路被断开，因此所有六个反应堆都与电网断开了17分钟。
当地时间下午12点29分，高架线路恢复，5号和6号反应堆再次开始运行。
当地时间下午2点14分，架空线路再次断开，关闭了6号反应堆，只剩下5号反应堆在运行。将6号机组重新接入电网的工作正在进行中。
国际原子能机构表示，暂时关闭进一步表明“迫切需要一个国际原子能机构专家团前往该设施。”

如果失去外部电源，冷却反应堆的水循环将停止，这将导致反应堆熔毁。然而，国际原子能机构在一份声明中表示，该核电站“仍与附近热电设施的330千伏线路相连，如果需要，该设施可以提供备用电力”。“由于750千伏电力线路被切断，ZNPP两个运行中的反应堆机组与电网断开，它们的应急保护系统被触发，而所有安全系统仍在运行。”
国际原子能机构表示:“目前还没有关于断电直接原因的信息。”。“拥有六个反应堆的ZNPP通常有四条外部电源线，但其中三条在冲突中丢失了。原子能机构将与乌克兰保持密切联系，并将尽快提供最新信息。”
乌克兰总统弗拉基米尔·泽伦斯基(Volodymyr Zelenskyy)周四警告说，“世界必须明白这是一个多么大的威胁:如果柴油发电机没有启动，如果工厂的自动化和工作人员在停电后没有做出反应，那么我们可能已经被迫克服辐射事故的后果。俄罗斯已经把乌克兰和所有欧洲人置于离辐射灾难只有一步之遥的境地。”
他呼吁国际原子能机构和其他国际组织更快地采取行动，“因为俄罗斯军队在核电站停留的每一分钟都是一场全球辐射灾难的风险。”
拜登，泽伦斯基在电话中讨论武器援助，核电厂
白宫新闻秘书郭佳欣·让-皮埃尔说，美国总统乔·拜登和乌克兰总统弗拉基米尔·泽伦斯基(Volodymyr Zelenskyy)周四在电话中谈到了武器援助和对扎波罗热核电站的担忧。
让-皮埃尔说，关于Zaporizhzhia，“我们已经说过，俄罗斯应该同意将工厂周围的地区非军事化，并同意尽快允许国际原子能机构的访问”。"这是在一次谈话中确实提到过的事情。"
泽伦斯基在推特上发布了一张他与拜登通话的照片，并表示他感谢拜登“美国对乌克兰人民坚定不移的支持-安全和金融。”
泽伦斯基说，他和拜登“讨论了乌克兰在战胜侵略者的道路上采取的进一步措施，以及让俄罗斯为战争罪行负责的重要性。”
拜登还在推特上发布了电话照片，并表示他祝贺乌克兰独立日，这一天是周三。
“我知道这是一个苦乐参半的周年纪念日，但我明确表示，美国将继续支持乌克兰及其人民捍卫主权的斗争，”拜登写道。

白宫称，俄罗斯可能在被占领的乌克兰领土举行虚假公投

白宫表示，美国认为俄罗斯可能在几天或几周内在被占领的乌克兰领土上举行“虚假公投”。
白宫发言人约翰·柯比(John Kirby)上个月表示，俄罗斯正在“在其控制下的乌克兰地区安插非法代理官员”，这些官员随后将安排“虚假公投”，作为吞并的前奏。
柯比星期三告诉记者，美国政府认为“这些公投可能在几天或几周内开始。”
柯比说:“我们有情报显示，俄罗斯继续准备在赫尔松、扎波罗热、所谓的顿涅茨克和卢甘斯克人民共和国举行这些虚假的公投。”。“我们还了解到，俄罗斯领导层已经指示官员开始准备举行这些虚假的公投，特别是在哈尔科夫。”
“我们预计俄罗斯会试图操纵这些公投的结果，谎称乌克兰人民希望加入俄罗斯，”他继续说道。"实时指出并反击这种虚假信息将是至关重要的."
“任何声称乌克兰人民想加入俄罗斯的说法都是不真实的，”柯比援引民调数据说。他补充说，很明显，乌克兰人“重视并珍惜他们的独立。”
柯比说，乔·拜登总统和乌克兰总统弗拉基米尔·泽伦斯基将于周四通电话。
Russia-Ukraine live updates: All reactors at power plant shut down for 1st time in history
Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military has since launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

All reactors at power plant shut down for 1st time in history
All of the reactors at Zaporizhzhia nuclear power plant, where shelling has been ongoing, have been shut down for the first time in the plant’s history, Ukraine's state nuclear regulator Energoatom reported.
Zaporizhzhia -- the largest nuclear power plant in Europe -- has six reactors, two of which are active, according to Ukraine's state nuclear regulator, Energoatom. At 12:12 p.m. local time, the last operating line providing power to the plant was disconnected due to hostilities in the area, and as a result all six reactors were disconnected from the grid for 17 minutes, Energoatom said.
At 12:29 p.m. local time the overhead line was restored and reactors Nos. 5 and 6 start operating again.
At 2:14 p.m. local time, the overhead line was disconnected again, shutting down reactor No. 6 and leaving only reactor No. 5 operating. Work is underway to reconnect No. 6 to the grid.
The International Atomic Energy Agency said the temporary shut down further shows "the urgent need for an IAEA expert mission to travel to the facility."
If external power is lost there's not active circulation of the water that cools the reactor and that could lead to a reactor meltdown. However, the plant "remained connected to a 330 kV line from the nearby thermal power facility that can provide back-up electricity if needed," the IAEA said in a statement. "As a result of the cuts in the 750 kV power line, the ZNPP’s two operating reactor units were disconnected from the electricity grid and their emergency protection systems were triggered, while all safety systems remained operational."
"There was no information immediately available on the direct cause of the power cuts," the IAEA said. "The six-reactor ZNPP normally has four external power lines, but three of them were lost earlier during the conflict. The IAEA remains in close contact with Ukraine and will provide updated information as soon as it becomes available."
Ukrainian President Volodymyr Zelenskyy warned Thursday, "The world must understand what a threat this is: If the diesel generators hadn’t turned on, if the automation and our staff of the plant had not reacted after the blackout, then we would already be forced to overcome the consequences of the radiation accident. Russia has put Ukraine and all Europeans in a situation one step away from a radiation disaster."
He called on the IAEA and other international organizations to act faster, "because every minute the Russian troops stay at the nuclear power plant is a risk of a global radiation disaster."
Biden, Zelenskyy discuss weapons assistance, nuclear plant during phone call
President Joe Biden and Ukrainian President Volodymyr Zelenskyy spoke about weapons assistance and concerns over the Zaporizhzhia nuclear plant in their phone call on Thursday, White House press secretary Karine Jean-Pierre said.
Regarding Zaporizhzhia, "We have said Russia should agree to demilitarize the zone around the plant and agree to allow an International Atomic Energy Agency visit as soon as possible," Jean-Pierre said. "This is something that did come up in a conversation."
Zelenskyy tweeted a photo of his phone call with Biden, and said he thanked him "for the unwavering U.S. support for Ukrainian people -- security and financial."
Zelenskyy said he and Biden "discussed Ukraine’s further steps on our path to the victory over the aggressor and importance of holding Russia accountable for war crimes."
Biden also tweeted a photo of the call, and said he congratulated Ukraine on its Independence Day, which was on Wednesday.
"I know it is a bittersweet anniversary, but I made it clear that the United States would continue to support Ukraine and its people as they fight to defend their sovereignty," Biden wrote.
21 killed in Russian missile strike on train station

Russia may hold sham referenda in occupied Ukrainian territory: White House
The White House said the U.S. believes Russia could hold "sham referenda" in occupied Ukrainian territory within days or weeks.
White House spokesman John Kirby said last month that Russia was "installing illegitimate proxy officials in the areas of Ukraine that are under its control" who would then arrange "sham referenda" as a precursor to annexation.
Kirby told reporters Wednesday that the U.S. government believes "these referenda could begin in a matter of days or weeks."
"We have information that Russia continues to prepare to hold these sham referenda in Kherson, Zaporizhzhia, the so-called Donetsk and Luhansk People's Republics," Kirby said. "We've also learned that Russian leadership has instructed officials to begin preparing to hold these sham referenda, particularly in Kharkiv, as well."
"We expect Russia to try to manipulate the results of these referenda to falsely claim that the Ukrainian people want to join Russia," he continued. "It will be critical to call out and counter this disinformation in real time."
"Any claim that the Ukrainian people somehow want to join Russia is simply not true," Kirby said, citing polling data. It's clear, he added, that Ukrainians "value and treasure their independence."
President Joe Biden and Ukrainian President Volodymyr Zelenskyy will speak on the phone on Thursday, Kirby said.
