Ukrainian president introduces martial law as Russia launches offensive

Russian troops launched their anticipated attack on Ukraine on Thursday, as President Vladimir Putin cast aside international condemnation and sanctions, warning other countries that any attempt to interfere would lead to “consequences you have never seen.”

Big explosions were heard before dawn in Kyiv, Kharkiv and Odesa as world leaders decried the start of a Russian invasion that could cause massive casualties and topple Ukraine’s democratically elected government. Beyond casualties that could overwhelm Ukraine’s government, the consequences of the conflict and resulting sanctions levied on Russia could reverberate throughout the world, affecting energy supplies in Europe, jolting global financial markets and threatening the post-Cold War balance on the continent.

In an apparent reference to Putin’s move to authorize the deployment of the Russian military to “maintain peace” in eastern Ukraine, Zelensky warned that “this step could mark the start of a big war on the European continent.”

At an emergency meeting of the U.N. Security Council called by Ukraine because of the imminent threat of a Russian invasion, members still unaware of Putin’s announcement appealed to him to stop an attack.
