At least 137 people including soldiers and civilians were killed on the first day of Russia’s intervention in Ukraine, Ukraine’s president said Friday.

Volodymyr Zelenskyy provided preliminary data on the death toll in a video message on Facebook, Ukraine’s official Ukrinform news agency reported.

He also said that “enemy sabotage groups” have entered the capital Kyiv and called on the public to be careful and follow curfew rules.

Donbas crisis and Russia’s military intervention

The February 2014 “Maidan revolution” in Ukraine led to former President Viktor Yanukovych fleeing the country and a pro-Western government coming to power.

That was followed by Russia illegally annexing the Crimea region and separatists declaring independence in the Donetsk and Luhansk regions of Donbas in eastern Ukraine, both of which have large ethnic Russian populations.

As clashes erupted between Russian-backed separatist forces and the Ukrainian army, the 2014 and 2015 Minsk Agreements were signed in Moscow after the intervention of Western powers.

The conflict, however, simmered for years with persistent cease-fire violations. As of February 2022, some 14,000 people have been killed in the conflict in eastern Ukraine.

Tensions started escalating late last year when Ukraine, the US and its allies accused Russia of amassing tens of thousands of troops on the border with Ukraine.

They claimed that Russia was preparing to invade its western neighbor, allegations that were consistently rejected by Moscow.

Defying threats of sanctions by the West, Moscow officially recognized Donetsk and Luhansk as independent states earlier this week, followed by the start of a military operation in Ukraine on Thursday.

Russian President Vladimir Putin said the operation aims to protect people “subjected to genocide” by Kyiv and to “demilitarize and de-Nazify” Ukraine, while calling on the Ukrainian army to lay down its arms. (Anadolu Agency)
