Russia-Ukraine conflict escalates with attacks on mainland routes and border infiltrators.

The Ukrainian army has destroyed Russia's mainland route to Crimea by targeting military targets in Berdyansk and Melitopol. These cities are part of the Russian mainland route to Crimea, which is used for munition supply. Explosions were heard in the Crimean city of Dzankoy, and Ukraine is preparing for a counteroffensive. Ukrainian demining units are clearing territories along the contact line in preparation for the offensive, which is predicted to have a "army-wide effect" by former CIA Director David Petraeus.
