#BTCBreaksATH While Russia's overnight drone and missile attacks on Ukraine have hit record levels, on the ground its military is claiming territorial gains.

Last month Russian forces seized 556 sq km (215 sq miles), its biggest land grab this year, according to the open-source DeepState monitoring website in Ukraine. That is an area four times the size of Liverpool and nearly the same size as the city of Chicago.

Russia's goal is to cut off supply routes used by Ukrainian troops in the east, and create a buffer zone inside Ukraine's northern borders.

But its advance remains relatively slow. At this pace it would take more than 70 years to capture the entire country.
