After months of escalating tensions, Russia launched a broad military attack on neighboring Ukraine in the early hours of Feb. 24. In a televised speech, Russian President Vladimir Putin said he had ordered a “special military operation” to defend ethnic Russians in the breakaway regions of Donetsk and Luhansk. The areas in eastern Ukraine are controlled by Moscow-backed separatists and were recognized Feb. 21 by Moscow as independent republics, a move which the EU denounced as a violation of international law. Ukrainian leadership has said at least 40 people have already been killed in what it called a “full-scale invasion” by Russian forces.

While Putin said the aim of the assault was to protect civilians in eastern Ukraine and to demilitarize (rather than occupy) Ukraine, the U.S. says Russia’s moves are intended to create a pretext for a wider invasion. Russian troops had been amassing at the Ukrainian borders for months.

Large explosions were reportedly heard Feb. 24 in the Ukrainian capital Kyiv, the northeastern city of Kharkiv, and other areas. Regional authorities in Odessa, a southern port city and key Ukrainian navy base, said that 18 people were killed in a missile attack.

“The people of Ukraine and the government of Ukraine want peace,” Ukrainian president Volodymyr Zelensky said, in Russian, in a direct appeal to Russia’s citizens. “But if we come under attack, if we face an attempt to take away our country, our freedom, our lives and the lives of our children, we will defend ourselves. When you attack us, you will see our faces, not our backs.”

Zelensky declared martial law early Feb. 24 and urged Ukrainians to stay at home and to remain calm. The Ukrainian leader said that he had asked for a call with Putin late Wednesday before the invasion, but that the Kremlin did not respond. Thousands of Ukrainian citizens have attempted to flee major cities, including Kyiv, while others have taken shelter in subway stations or makeshift bunkers.

World leaders quickly condemned Moscow’s actions, which U.S. President Joe Biden called “unprovoked and unjustified.” Following the invasion, the E.U. announced a raft of sanctions against Russia “designed to take a heavy toll on the Kremlin’s interests and their ability to finance war.”

Although Ukraine has existed for over three decades as an independent nation-state, in Putin’s eyes the former Soviet state is an integral part of Russia’s “own history, culture, spiritual space.” In an attempt to rewrite history, the Russian leader said Feb. 21 that Ukraine never had “real statehood.” Ukraine had expressed a desire to join the military alliance NATO, a suggestion which Moscow condemned.

Here’s a roundup of the most powerful images which tell the story of the first days of Russia’s invasion.
