Russia-Ukraine live updates: Russia launches attacks on Ukraine

The U.S. Ambassador to the United Nations said Wednesday night that Russia has brought the world “to the brink of a conflict that will produce an untold amount of human suffering," as leaders gathered for an emergency meeting of the U.N. Security Council.

U.S. Ambassador Linda Thomas-Greenfield said officials believe a “full-scale further invasion into Ukraine by Russia is imminent," with Russia closing airspace and moving its forces into “combat ready positions.” She also described reports of malware “placed on hundreds of computers and executed on at least some."

“This is a perilous moment,” she said. “And we are here for one reason, and one reason only. To ask Russia to stop. Return to your borders." She joined other countries in condemning Russia’s actions and said its diplomats have “laughed in the face" of human suffering.

Earlier, United Nations Secretary-General António Guterres said he had never believed rumors of an imminent attack on Ukraine, “convinced that nothing serious would happen.”

“I was wrong,” he said.

He acknowledged that “an operation is being prepared" and addressed Russian President Vladimir Putin, looking into the camera.

“From the bottom of my heart, President Putin, stop your troops from attacking Ukraine," Guterres said. "Give peace a chance. Too many have already died.”

The Security Council has five permanent members: China, France, Russia, the United Kingdom and the United States.

With the world absorbed by months of geopolitical brinkmanship, high-stakes diplomacy and scrutiny of Russia’s military encirclement of Ukraine, lost in the din has been this sobering fact: If President Vladimir Putin proceeds with a large-scale invasion, thousands will probably die.

U.S. officials estimate a major assault could leave as many as 50,000 civilians dead or wounded, as Western nations warn of Putin’s intent to drive deeper into the former Soviet state.

Experts and humanitarian groups have assessed the conflict could take a particularly devastating toll on noncombatants due to Moscow’s massive arsenal, its record of targeting civilians and the wider potential for punishing urban battles. Such a state-to-state showdown would represent a break from the insurgencies of recent decades, one that could usher in a new era of deadly modern warfare.

As the United States seeks to rally its allies and impose tough penalties for Russia’s aggression toward Ukraine, a vocal group of Republicans and right-leaning commentators is expressing praise and admiration for the president’s strength and shrewdness. President Vladimir Putin, that is.

While most congressional Republicans back Biden’s tough line against Moscow — or argue it should be even tougher — a faction made up of conservative Republicans, supporters of former president Donald Trump and conservative media figures says Putin should be left alone, or even congratulated, by Americans.

Trump complimented Putin on Tuesday, saying it was a “smart move” by the Russian president to send “the strongest peace force I’ve ever seen” to the Ukraine border.

Russian forces are “at the final point of readiness” for a full-scale invasion of Ukraine, U.S. Secretary of State Antony Blinken said Wednesday night on NBC News.

“Everything seems to be in place for Russia to engage in a major aggression against Ukraine,” he told NBC Nightly News anchor Lester Holt.

Holt had asked if Blinken had “reason to believe that before this night is over Russian forces will be engaged in something akin to a full invasion of Ukraine.” Blinken said yes, but soon clarified that he “can’t put a date or an exact time” on such an escalation.

Speaking on CBS Evening News, Blinken pushed back on suggestions that warnings of an imminent invasion signal a “failure of American diplomacy.”

“To the contrary — first of all, diplomacy succeeded very effectively in bringing the world together, the United States and Europe together, in standing up to Russian aggression,” Blinken told anchor Norah O’Donnell. “At the same time, we’ve made it clear that if Russia continues to escalate, if it engages in a full-scale invasion of Ukraine beyond what it’s already doing, we’ll escalate too.”

He noted Germany’s decision to halt authorization of a natural gas pipeline from Russia, a major project that Blinken said Russia “was counting on to be a cash cow for selling energy to Europe.”

“Why is … the world going to wait for this to happen?” O’Donnell asked. “And do you believe Putin will stop at Ukraine?”

Blinken insisted: “We’re not waiting. We’re acting.”

The U.N. Security Council will hold an emergency meeting in New York on Wednesday night in a session requested by Ukraine, said a U.N. diplomat familiar with the matter.

The push for the gathering — which is expected to begin at 9:30 p.m. Eastern time — comes amid fears of a Russian military invasion deep into Ukraine and beyond its separatist regions of Donetsk and Luhansk. Russia is currently the president of the Security Council.

The meeting is expected to be open and televised, said the diplomat, who spoke on the condition of anonymity to discuss sensitive diplomatic moves.

Earlier on Wednesday, Ukrainian Foreign Minister Dmytro Kuleba said that his country had requested an urgent meeting of the Security Council in response to the Kremlin claiming that two separatist leaders had asked Russia for help in countering Ukrainian forces’ “aggression.”

Kuleba tweeted that the plea was “due to the appeal by Russian occupation administrations in Donetsk and Luhansk to Russia with a request to provide them with military assistance, which is a further escalation of the security situation.”

Ukraine denies any aggression, and the United States and the West have characterized these claims as false-flag operations that are a possible pretense for a full-scale military invasion.

Americans are paying nearly a dollar more for a gallon of gas — to roughly $5 in some markets — than they did last year as the growing threat of war in Ukraine moved oil prices higher.

The U.S. average for regular unleaded gasoline hit $3.53 gallon on Wednesday, according to AAA. That’s 21 cents higher than last month and a hefty jump from the $2.65 recorded a year ago.

Oil prices climbed as the Russia-Ukraine crisis played out, pushing them within striking distance of $100 a barrel. They’ve eased slightly, with Brent crude, the international benchmark, trading Wednesday at roughly $97 a barrel and West Texas Intermediate, the U.S. benchmark, hovering above $92. But both are up about 40 percent from their early December low points.

A previously unknown strain of malicious software appeared on hundreds of computers in Ukraine on Wednesday and began destroying data, security experts said.

Jean-Ian Boutin, head threat researcher at the Slovakia-based security firm ESET, which first reported the detections, said that the malware was “very effective” and had been used against large organizations. It had probably been used against many more companies that had not reported it, he added.

Another security firm, Broadcom’s Symantec, confirmed that the malware hit at least three organizations, including a bank and two government contractors.

Vikram Thakur, technical director for Symantec’s threat intelligence division, said that it was probably more widespread but that Symantec security software was not installed as widely in Ukraine as in other markets and therefore could not detect many of the infections.

Boutin said it was not clear how the malware had been deployed or if it took advantage of new or known security flaws. Time stamps indicated the software had been created two months ago, he said.

ESET did not attribute the software to any specific actor, but Boutin said he assumed it was related to the conflict between Ukraine and Russia, which has used similar malware against Ukrainian targets in past years.

Other experts said they expected a variety of computer attacks to escalate. “There will likely be a long campaign of cyberattacks against Ukrainian targets,” said John Hultquist, vice president of security firm Mandiant. “The financial sector appears to be a consistent target of these efforts, which could be designed to undermine confidence.”

Meanwhile, the Ukraine government’s cyber-service warned of an increase in “destructive actions” and urged technology professionals to isolate “all workstations and servers that are not related to critical functions in the interests of citizens, businesses and the state.”

The agency said operators should update their systems to the latest versions and back up critical information to external storage.

Ukrainian President Volodymyr Zelensky spoke directly to the Russian people during an emotional video address late Wednesday, warning them the Kremlin had approved the movement of nearly 200,000 forces into Ukrainian territory in what could “become the start of a big war on the European continent.”

Zelensky, speaking in Russian, said he attempted to call President Vladimir Putin earlier in the day but was met with silence. The Ukrainian president said Russia and Ukraine share more than 2,000 kilometers of border that is now lined with nearly 200,000 Russian troops and thousands of armored vehicles.

“Your leadership has approved them to move forward onto the territory of another country,” Zelensky warned. “This step could become the start of a big war on the European continent.”

Zelensky warned the Russian people that they were being duped by what they are hearing on Russian state news channels. “You are being told that this is a plan to free the people of Ukraine,” he said. “But the Ukrainian people are free.”

His voice laden with emotion and anger, Zelensky aggressively challenged the image of Ukraine projected onto the televisions of Russians through Kremlin-controlled news.

“The Ukraine on your news and the Ukraine in real life are two completely different countries — and the main difference is that ours is real,” Zelensky said. “You are being told that we are Nazis. How could a people that lost more than 8 million people in the fight against Nazism support Nazism?”

“How could I be a Nazi?” said Zelensky, who is Jewish, citing his grandfather’s service in the Soviet army fighting the Germans during World War II.

Zelensky said that even though Russians and Ukrainians have differences, that is not a reason to be enemies.
