乌克兰首席谈判代表:“已经是WWIII了”
乌克兰总统弗拉基米尔·泽伦斯基(Volodymyr Zelenskyy)办公室的顾问、乌克兰-俄罗斯谈判的首席谈判代表米哈伊洛·波多利亚克(Mykhailo Podolyak)敦促世界各国领导人对俄罗斯在乌克兰引发的冲突采取立场，称第三次世界大战已经在我们中间爆发。
“已经是第三次世界大战了——世界领导人现在必须选择他们的立场，”波多利亚克告诉美国广播公司新闻。“每个国家的每个领导人都必须解释，为什么在俄罗斯炮轰乌克兰平民儿童的时候，他会站在一边。”
他说，波多利亚克对谈判的进展持“谨慎乐观”的态度，并补充说，乌克兰不会向俄罗斯做出任何让步。
“我的谨慎乐观是基于这样一个事实，即他们明白他们不会击垮我们，他们也没有足够的资源来应对他们开始的事情，”他说。
波多利亚克说，尽管有他所谓的“俄罗斯宣传”报道，但周日在利沃夫郊区的亚沃利夫的袭击中，没有外国战士丧生。他指责俄罗斯利用停火——实施停火是为了建立人道主义走廊——来重组和重新定位自己，以便进行战略攻击。
此外，对乌克兰南部平民的轰炸和炮击继续加剧，Podolyak说。
Podolyak说，乌克兰和俄罗斯之间的更多谈判定于明天举行。

红十字会:数千名被困在马里乌波尔的平民可能遭遇“最糟糕的情况”
红十字国际委员会呼吁紧急解决被困在马里乌波尔的数十万平民面临的“生死攸关”的局面，他们没有自来水和电力，因为俄罗斯军队的猛烈空袭仍在继续。
红十字国际委员会周日在一份新闻稿中表示，除非交战各方立即达成人道主义协议，否则“最糟糕的情况”将等待那些留在城里的人。
“我们呼吁参与战斗的所有各方把人道主义需要放在首位。马里乌波尔的人们经历了长达一周的生死噩梦。现在需要停止这种行为，”红十字国际委员会主席彼得·毛雷尔在一份声明中说。"他们的安全以及获得食物、水和住所的权利必须得到保障."
据红十字会称，包括红十字会工作人员在内的所有年龄段的人都躲在没有暖气的地下室里，冒着生命危险跑到外面去寻找食物和水。
平民和战斗人员的尸体仍然被困在瓦砾下或躺在他们倒下的空地上，受伤或患有慢性虚弱疾病的人无法寻求治疗。
“战争的声音是不变的。建筑物被击中，弹片四处乱飞，”红十字国际委员会在马里乌波尔的行动负责人萨沙·沃尔科夫说。“这是这个城市每个人面临的情况。”
Russia-Ukraine updates: American in western Ukraine describes 'bombs falling left and right'
Russian forcesare continuing their attempted push through Ukrainefrom multiple directions, while Ukrainians, led by President Volodymyr Zelenskyy, are putting up "stiff resistance," according to U.S. officials.
The attack began Feb. 24, when Russian President Vladimir Putin announced a "special military operation."
Russian forces moving from neighboring Belarus toward Ukraine's capital, Kyiv, have advanced closer to the city center in recent days despite the resistance, coming within about 9 miles as of Friday.
Russia has been met by sanctions from the United States, Canada and countries throughout Europe, targeting the Russian economy as well as Putin himself.
Mariupol humanitarian corridor blocked again, Zelenskyy says
undefinedundefinedundefinedundefined
The humanitarian corridor established for civilians fleeing the city of Mariupol was blocked again Sunday as Russian forces cast relentless airstrikes on the city, Ukrainian President Volodymyr Zelenskyy said in an address.
Zelenskyy continued to appeal for NATO to establish a no-fly zone in the region, saying NATO countries are next if it is not done soon.
“If you do not close our sky, it is only a matter of time before Russian missiles fall on your territory,” Zelenskyy warned NATO.
In western Ukraine, 30 missiles hit the region around Lviv, where the shelling of the International Center for Peacekeeping and Security killed 35 people and wounded 134 others, Zelenskyy said.
At least 10 humanitarian corridors operated in the Kyiv and Luhansk regions on Sunday, Zelenskyy said.
Lead Ukrainian negotiator: 'It’s already WWIII'
Mykhailo Podolyak, an adviser to the office of Ukrainian President Volodymyr Zelenskyy and the lead negotiator in Ukraine-Russia talks, is urging world leaders to take a stance on the conflict Russia has sparked in Ukraine, saying the third world war is already among us.
"It’s already World War III –- world leaders must now choose their side," Podolyak told ABC News. "Every leader of every country must explain why he will stand to the side at the time when Russia was shelling civilian children in Ukraine."
Podolyak is "cautiously optimistic" that negotiations are progressing, he said, adding that Ukraine will not offer any concessions to Russia.
"My cautious optimism is based on the fact that they understand they will not break us and they will not have enough resources to answer what they started," he said.
Podolyak said that, despite what he described as "Russian propaganda" reports, no foreign fighters were killed during the strike on Yavoriv, on the outskirts of Lviv, on Sunday. He accused Russia of using the ceasefire -- which was implemented to establish humanitarian corridors -- to regroup and reposition themselves for strategic attacks.
In addition, the bombing and shelling of civilians in Southern Ukraine continues to intensify, Podolyak said.
More negotiations between Ukraine and Russia are schedule to take place tomorrow, Podolyak said.
Nearly 2.7 million people have left Ukraine
The United Nations High Commissioner for Refugees has calculated that 2,698,280 people have fled Ukraine since Feb. 24 as a result of the Russian invasion.
About 1.66 million people have entered Poland, 246,206 people have entered Hungary, and 195,980 people have entered Slovakia.
Nearly 200,000 people have entered Russia, Moldova, Romania and Belarus combined, while more than 304,000 people have entered other European countries.
'Worst-case scenario' possible for thousands of civilians trapped in Mariupol: Red Cross
The International Committee of the Red Cross is calling for an urgent solution for the "life-and-death" situation facing the hundreds of thousands of civilians trapped in Mariupol without access to running water and electricity as the heavy airstrikes from Russian forces continue.
A "worst-case" scenario awaits those who remain in the city unless a humanitarian agreement among the fighting parties is reached immediately, the ICRC said in a press release on Sunday.
"We call on all parties involved in the fighting to place humanitarian imperatives first. People in Mariupol have endured a weekslong life-and-death nightmare. This needs to stop now," Peter Maurer, president of the ICRC, said in a statement. "Their safety and their access to food, water and shelter must be guaranteed."
People of all ages, including Red Cross staff, are sheltering in unheated basements and risking their lives to make short runs outside for food and water, according to the ICRC.
Dead bodies, both of civilians and combatants, remain trapped under the rubble or lying in the open where they fell, and those suffering injuries or chronic, debilitating conditions are unable to seek treatment.
"The sound of warfare is constant. Buildings are struck, and shrapnel flies everywhere," said ICRC's operational leader in Mariupol, Sasha Volkov. "This is the situation every person in the city faces."
