美国继续警告俄罗斯可能入侵乌克兰”随便哪一天在该地区紧张局势不断升级的情况下，美国总统乔·拜登周四告诉记者，威胁现在“非常高”。"

美国国务卿安东尼·布林肯周四在联合国安理会发表紧急讲话，要求莫斯科承诺不入侵。

美国官员说，估计有超过15万俄罗斯军队集结在乌克兰边境附近。虽然俄罗斯总统弗拉基米尔·普京和克里姆林宫声称一些部队已经开始撤离，但拜登告诉记者，与莫斯科的说法相反，更多的俄罗斯部队已经进入。

目前还不清楚普京是否已经决定攻击他的前苏联邻居。

俄罗斯否认有任何入侵计划，并重申其要求美国和北约阻止乌克兰加入军事联盟。

美国指控俄罗斯将乌克兰人列入“被杀或送往集中营”的名单

美国获得了俄罗斯针对乌克兰目标的潜在行动的信息，作为潜在入侵的一部分，包括定点清除、绑架、拘留和酷刑，美国在ABC新闻获得的一封给联合国的信中声称。

美国大使芭丝谢芭·内尔·克罗克(Bathsheba Nell Crocker)写信给联合国人权事务高级专员米歇尔·巴切莱特(Michelle Bachelet)，称“我们有可靠信息表明，俄罗斯军队正在建立一份名单，上面列有在军事占领后被杀害或送往集中营的乌克兰人的身份。”

克罗克写道，这包括“可能使用”致命手段来“驱散和平抗议者，或以其他方式对抗平民感知的抵抗和平演习”。

美国国务卿安东尼·布林肯(Antony Johnson)周四在联合国安理会(U.N. Security Council)的讲话中暗示了这一点，他告诉他的外交官同事，“俄罗斯计划对乌克兰人民实施的不仅仅是常规攻击。我们有情报显示，俄罗斯将针对特定的乌克兰人群体。”

此外，消息人士上周二告诉美国广播公司新闻，美国认为俄罗斯旨在进入基辅，以推翻乌克兰政府并建立自己的政府。

但这封新信件走得更远，称俄罗斯“可能会针对那些反对俄罗斯行动的人，包括流亡乌克兰的俄罗斯和白俄罗斯异见人士、记者和反腐败活动人士，以及宗教和少数民族以及LGBTQI+人士等弱势群体。”

美国国务院周日宣布，美国负责国际组织的最高外交官米歇尔·西松大使本周将前往日内瓦，在联合国总部会见巴切莱特。

“美国严重关切俄罗斯进一步入侵乌克兰会造成广泛的人类痛苦。鉴于人权高专办的重要任务及其在乌克兰的报道存在，我们希望与你分享这一信息，作为俄罗斯进一步入侵乌克兰可能造成人权灾难的预警，”克罗克在信中补充道。

拜登和普京同意举行峰会

美国总统拜登和俄罗斯总统弗拉基米尔·普京同意举行由法国总统埃马纽埃尔·马克龙提议的峰会。两位领导人都“原则上”接受了峰会，但有一个主要条件:俄罗斯不得入侵乌克兰。

白宫新闻秘书珍·普萨基周日晚上在一份声明中说:“正如总统一再明确表示的那样，我们致力于寻求外交途径，直到入侵开始的那一刻。”

美国国务卿布林肯和俄罗斯外长拉夫罗夫定于星期四会晤。根据法国政府的一份声明，在会议期间，他们将准备峰会的“实质内容”。马克龙也“将与所有利益攸关方合作，准备这些讨论的内容”。

马克龙周日与普京通了两次电话，在他打电话给拜登进行简短的15分钟电话之前和之后。

普萨基说:“我们随时准备进行外交努力。”。“如果俄罗斯选择战争，我们也准备好施加迅速和严重的后果。目前，俄罗斯似乎正在继续准备很快对乌克兰发动全面进攻。”

美国国务院提供更多关于莫斯科安全警报的信息

美国国务院发言人表示，周日发布的警告警告美国人避开人群，在游客和西方人经常去的地方保持警惕，这是“出于大量的谨慎”，没有将其与俄罗斯-乌克兰危机直接联系起来。

发言人在一份声明中说:“最近几天，一些俄罗斯媒体报道了针对俄罗斯公共建筑的一系列炸弹威胁，包括莫斯科、圣彼得堡和其他地方的地铁站。”

“美国国务院没有比海外美国公民的安全和安保更大的责任，”他们说。“出于充分的谨慎，并符合我们为美国公民提供明确和及时信息的承诺，以便他们能够做出明智的旅行决定，我们发布了这一警告。”

拜登召开国家安全委员会会议

白宫发布了乔·拜登(Joe Biden)总统周日召集国家安全委员会就乌克兰和俄罗斯的军事集结召开的会议的一句话，证实了这次会议的召开。

“今天，小约瑟夫·拜登总统召开了国家安全委员会会议，讨论俄罗斯在乌克兰边境军事集结的最新进展，”声明全文称。

一名白宫官员告诉美国广播公司新闻，会议持续了两个多小时，白宫发布的一张会议照片显示，中央情报局局长威廉·伯恩斯、参谋长联席会议主席马克·米利、国防部长劳埃德·奥斯丁、国务卿安东尼·布林肯、国家安全顾问杰克·沙利文、财政部长珍妮特·耶伦和国土安全顾问利兹·舍伍德-兰德尔。桌子上还可以看到DNI·艾薇儿·海恩斯和参谋长罗恩·克莱恩的名牌。

据一名白宫官员称，照片中没有出现的还有副总统卡玛拉·哈里斯，他通过空军二号与能源部部长詹妮弗·格兰霍姆和商务部长吉娜·雷蒙多进行了电话联系。该官员补充说，鉴于格兰霍尔姆、雷蒙多和耶伦在制裁、出口管制和能源方面的角色，他们参加了会议。

此外，白宫周日表示，拜登从美国东部时间下午3点47分至下午4点02分与法国总统埃马纽埃尔·马克龙进行了15分钟的通话。此前，俄罗斯总统弗拉基米尔·普京和乌克兰总统泽伦斯基于周日早些时候举行了会谈。

Russia-Ukraine live updates: Biden, Putin agree to summit later this week

The United States continues to warn that Russia could invade Ukraine "any day" amid escalating tensions in the region, with President Joe Biden telling reporters Thursday that the threat is now "very high."

U.S. Secretary of State Antony Blinken on Thursday, making urgent remarks to the United Nations Security Council, challenged Moscow to commit to no invasion.

More than 150,000 Russian troops are estimated to be massed near Ukraine's borders, U.S. officials have said. While Russian President Vladimir Putin and the Kremlin claim that some troops have begun to withdraw, Biden told reporters that more Russian forces have moved in, contrary to Moscow's claims.

It remains unclear whether Putin has made a decision to attack his ex-Soviet neighbor.

Russia has denied any plans to invade and reiterated its demands that the U.S. and NATO bar Ukraine from joining the military alliance.

US alleges Russia making list of Ukrainians ‘to be killed or sent to camps’

The United States has obtained information ofpotential Russian operations against Ukrainian targets as part of a potential invasion, including targeted killings, kidnappings, detentions and torture, the U.S. alleged in a letter to the United Nations obtained by ABC News.

“We have credible information that indicatesRussian forces are creating lists of identified Ukrainians to be killed or sent to camps following a military occupation,” U.S. Ambassador Bathsheba Nell Crocker wrote to Michelle Bachelet, the U.N. high commissioner for human rights.

That includes the “likely use” of lethal measures to “disperse peaceful protesters or otherwise counter peaceful exercises of perceived resistance from civilian populations,” Crocker wrote.

Secretary of State Antony Blinken alluded to this during his remarks to the U.N. Security Council on Thursday, telling his fellow diplomats, “Conventional attacks are not all that Russia plans to inflict upon the people of Ukraine.We have information that indicates Russia will target specific groups of Ukrainians.”

In addition, sources told ABC News last Tuesday that the U.S. believed Russia aimed to move into Kyiv to decapitate the Ukrainian government and install their own.

But this new letter goes further, saying Russia “would likelytarget those who opposes Russian actions, including Russian and Belarusian dissidents in exile in Ukraine, journalists and anti-corruption activists, and vulnerable populations such as religious and ethnic minorities and LGBTQI+ persons.”

Ambassador Michele Sison, the top U.S. diplomat for international organizations, is headed to Geneva this week to meet Bachelet at the U.N. headquarters there, the State Department announced Sunday.

“The United States is gravely concerned that a further Russian invasion of Ukraine would produce widespread human suffering. In light of OHCHR’s important mandate and its reporting presence in Ukraine, we wish to share this information with you as an early warning that a further Russian invasion of Ukraine may create a human rights catastrophe,” Crocker added in the letter.

Biden, Putin agree to summit

U.S. President Joe Biden and Russian President Vladimir Putin have agreed to hold a summit proposed by French President Emmanuel Macron. The leaders both accepted the summit “in principle,” with one major condition: that Russia does not invade Ukraine.

“As the president has repeatedly made clear, we are committed to pursuing diplomacy until the moment an invasion begins,” White House press secretary Jen Psaki said in a statement Sunday evening.

U.S. Secretary of State Antony Blinken and Russian Foreign Minister Lavrov are set to meet Thursday.During their meeting, they will prepare “the substance” of the summit, according to a statement from the French government. Macron “will work with all stakeholders to prepare the content of these discussions” as well.

Macron spoke with Putin twice Sunday, both before and after he called Biden for a brief 15-minute phone call.

“We are always ready for diplomacy,” Psaki said. “We are also ready to impose swift and severe consequences should Russia instead choose war.Andcurrently, Russia appears to be continuing preparations for a full-scale assault on Ukraine very soon.”

US State Department gives more info on Moscow safety alert

A State Department spokesperson said the alert published Sunday warning Americans to avoid crowds and stay alert in places frequented by tourists and Westerners was issued “out of an abundance of caution,” stopping short of tying it directly to the Russia-Ukraine crisis.

“In recent days a number of Russian media outlets have reported on a spate of bomb threats being made against Russian public buildings, including metro stations, in Moscow, St. Petersburg, and elsewhere,” the spokesperson said in a statement.

“TheU.S.Department of State has no greater responsibility than the safety and security ofU.S. citizens overseas,” they said.“Outof an abundance of caution, and in line with our commitment toprovidingU.S. citizens with clear and timely information so they can make informed travel decisions, we published this alert.”

Biden has National Security Council meeting

The White House released a one-sentence readout of President Joe Biden’s meeting that he convened of his National Security Council on Sunday over Ukraine and Russia’s military buildup, confirming that the meeting happened.

"Today, President Joseph R. Biden, Jr. convened a meeting of the National Security Council to discuss the latest developments regarding Russia’s military buildup on the borders of Ukraine," the statement said in full.

The meeting lasted just over two hours, a White House official told ABC News, and a photo of the meeting tweeted by the White House showed CIA Director William Burns, Chairman of the Joint Chiefs Mark Milley, Secretary of Defense Lloyd Austin, Secretary of State Antony Blinken, National Security Advisor Jake Sullivan, Treasury Secretary Janet Yellen, and Homeland Security Advisor Liz Sherwood-Randall. Name plates for DNI Avril Haines and Chief of Staff Ron Klain can also be seen on the table.

Also joining but not visible in the photo were Vice President Kamala Harris, who connected via phone from Air Force Two, Secretary of Energy Jennifer Granholm and Commerce Secretary Gina Raimondo, according to a White House official. Granholm, Raimondo and Yellen joined the meeting given their roles in sanctions, export controls and energy, the official added.

Additionally on Sunday, the White House said Biden spoke with French President Emmanuel Macron for 15 minutes from 3:47 p.m. ET to 4:02 p.m. ET. This followed with Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy earlier Sunday.
