WATCH: Ambassador Markarova says Ukrainians will fight Russia

The Ukrainian Ambassador to the United States says that her fellow citizens will fight Russia for their country.

Watch Markarova’s remarks in the player above.

Ambassador Oksana Markarova called Russia’s actions on Thursday a “war against Ukraine” and called on world leaders including U.S. President Joe Biden to cut all ties with Russia and level even more severe sanctions.

This comes after Russia launched a wide-ranging attack on Ukraine, hitting cities and bases with airstrikes or shelling, as civilians piled into trains and cars to flee.

Ukraine’s government pleaded for help as it said Russian tanks and troops rolled across the border in a “full-scale war” that could rewrite the geopolitical order.

President Vladimir Putin ignored global condemnation and cascading new sanctions as he unleashed Moscow’s most aggressive action since the 1979 Soviet invasion of Afghanistan, and chillingly referred to his country’s nuclear arsenal.

He threatened any foreign country trying to interfere with “consequences you have never seen.”

The chief of the NATO alliance said the “brutal act of war” shattered peace in Europe, joining a chorus of world leaders who decried the attack, which could cause massive casualties, topple Ukraine’s democratically elected government and upend the post-Cold War security order.

The conflict was already shaking global financial markets: Stocks plunged and oil prices soared amid concerns that heating bills and food prices would skyrocket.

Condemnation rained down not only from the U.S. and Europe, but from South Korea, Australia and beyond – and many governments readied new sanctions. Even friendly leaders like Hungary’s Viktor Orban sought to distance themselves from Putin.

While some nervous Europeans speculated about a possible new world war, the U.S. and its NATO partners have so far shown no indication they would join in a war against Russia. They instead mobilized troops and equipment around Ukraine’s western flank – as Ukraine pleaded for defense assistance and help protecting its airspace.
