The New York Times reports shortly after President Vladimir V. Putin announced military operations in Ukraine, blasts and explosions from missile attacks were reported in multiple parts of the nation of about 41 million people.

The war began around 5 a.m. Kyiv time on Thursday, Feb. 24.

Russian forces reportedly have attacked along three fronts — moving against Kyiv in the north, landing in the southern seaport of Odessa and attacking along the eastern border. Footage of tanks and troop carriers moving into the nation have been posted from border crossings.

Ukraine military forces have worked to defend the nation. The New York Times reported at least 40 Ukraine personnel have been killed in the fighting. Ukraine military claims to have destroyed multiple Russian aircraft and tanks.

Reuters reports this is the “biggest attack by one state against another in Europe since World War II.”

Sen. Susan Collins, R-Maine, released a statement Thursday morning, saying, “Putin’s attempts to recreate the old Soviet Union have been rejected by people who have chosen freedom and democracy.  So now he has resorted to brute military force against a peaceful country that posed no threat to Russia.  He has once again shown himself to be a ruthless autocrat who does not hesitate to kill innocent people while trampling international law.”

Sen. Angus King, I-Maine, also released a statement Thursday, saying, ““Vladimir Putin has single-handedly decided to end decades of peace among the nations of Europe on the basis of invented grievances and outright lies. His weakness of character will not be rewarded. Ukraine will stand strong, and the United States, our Allies, and our partners in the free world will stand with them to ensure that Russia feels the consequences of its invasion. This attack will not achieve Putin’s goal to seemingly reconstitute the Soviet Union; it will only create unnecessary human suffering. Let’s be clear: an unprovoked attack is not a defensive maneuver, armed soldiers invading a free, sovereign country are not “peacekeepers,” and not one of Russia’s missile strikes or cyberattacks will help Ukrainians. As we push to ensure that Russia pays a dire price for these heinous attacks, I’m praying for the people of Ukraine who are needlessly caught in the sights of a dictator’s delusions.”

The United States has joined other nations in condemning the attacks and has more than 5,000 troops stationed in Poland, which will be helping refugees fleeing from Ukraine. European Union and NATO partners are responding to the crisis.

In addition to concerns about potential escalation of global conflicts arising from this war, U.S. citizens may be impacted economically in the fallout. The New York Times has also reported that the war may further increase inflation and fuel prices.
