Russia pressed its invasion of Ukraine to the outskirts of the capital Kyiv Friday after unleashing airstrikes on cities and military bases and sending in troops and tanks from three sides in an attack that could rewrite the global post-Cold War security order.

Explosions sounded before dawn in Kyiv as Western leaders scheduled an emergency meeting and Ukraine’s president pleaded for international help. The nature of the explosions was not immediately clear, but the blasts came amid signs that the capital and largest Ukrainian city was increasingly threatened following a day of fighting that left more than 100 Ukrainians dead.

Ukraine President Volodymyr Zelenskyy said the government had information that “subversive groups” were encroaching on the city, and U.S. Secretary of State Antony Blinken said Kyiv “could well be under siege” in what U.S. officials believe is a brazen attempt by Russian President Vladimir Putin to dismantle the government and replace it with his own regime.

U.S. Defense Secretary Lloyd Austin told lawmakers on a phone call Thursday evening that Russian mechanized forces that entered from Belarus were about 20 miles from Kyiv, according to a person familiar with the call.

The assault, anticipated for weeks by the U.S. and Western allies and undertaken by Putin in the face of international condemnation and cascading sanctions, amounts to the largest ground war in Europe since World War II.

Russian missiles bombarded cities and military bases in the first day of the attack, and Ukraine officials said they had lost control of the decommissioned Chernobyl nuclear power plant, scene of the world’s worst nuclear disaster. Civilians piled into trains and cars to flee and patrons of a hotel were directed into a shelter as explosions sounded in Kyiv.

“Russia has embarked on a path of evil, but Ukraine is defending itself and won’t give up its freedom,” Zelenskyy tweeted. His grasp on power increasingly tenuous, he called Thursday for even more severe sanctions than the ones imposed by Western allies and ordered a full military mobilization that would last 90 days.

Zelenskyy said in a video address that 137 “heroes,” including 10 military officers, had been killed and 316 people wounded. The dead included border guards on the Zmiinyi Island in the Odesa region, which was taken over by Russians.
