It has been a year since Russian President Vladimir Putin launched the "special military operation" in Ukraine on February 24, 2022, the largest military actions since the end of the World War II in Europe. 

The Russia-Ukraine conflict has aggravated a global food crisis which has already been driven by extreme weather and the COVID-19 pandemic. Russia and Ukraine are the first and fifth largest wheat exporters, and both play a critical role in supplying agricultural products to global markets. 

The conflict has also created shock waves in global energy markets, leading to price volatility, supply shortages, security issues and economic uncertainty. Russia is one of the world's top three crude producers and the world's second-largest producer of natural gas. 

Russia is trying to regain the initiative while Ukraine relies on Western tanks to mount a counteroffensive later in 2023. There are no signs of a way out of the conflict, which has fueled fears that it could slide into an open confrontation between Russia and NATO.  

Here is a look at some of the key moments in the conflict.
