Russia retaliates against latest sanctions

(CNN) – On the border between Russia and Ukraine, the violence continues unabated.

Russian leader Vladimir Putin tried his best Wednesday to swing back at fresh sanctions from the United States and the European Union with his own attempt at causing economic havoc for his enemies.

All of this, as explosions echo across the region, and Russia bolsters its troop levels along the border.

CNN's Nick Paton Walsh reports about Putin's latest move, and the kind of destruction he is witnessing in Ukraine.
