RFE/RL reports:

Early in the morning on April 27, a drone crashed in a muddy field southwest of the Russian city of Kursk, around 100 kilometers northeast of the border with Ukraine. Locals tracked down the destroyed device not long after, and posted photographs to Telegram and other social media.

It wasn’t the Russians who were flying the drone.

And that wasn’t the only unusual thing that happened in that part of Russia that same morning: There were also two unexplained explosions at Russian military and industrial sites — one in Kursk and one near Voronezh, not far to the east.

Since February 24, Russian forces have laid waste to towns and cities in northern, eastern, and southern Ukraine, killing thousands of civilians and forcing millions to flee in a war that prompted the West to punish Moscow with sanctions and send massive supplies of military aid and support to Kyiv.

Ukrainian forces thwarted an offensive aimed at taking Kyiv in the war’s early weeks, prompting Russian troops to withdraw from close to the capital. Much of the fighting is now focused on the region known as the Donbas and other areas in the east and south.
