While reporting for "OutFront" on Tuesday evening, CNN's Nick Paton Walsh witnessed nearby gunfire in Donetsk, Ukraine.
As fight ensued during the early hours of the morning, Walsh noted that this was "the most sustained gunfire we’ve heard" near the center of the city.
This comes as the Russian military is nearly doubling in size along the border with Ukraine.
Watch the video above as Nick Paton Walsh pauses multiple times to acknowledge a barrage of gunfire.
The crisis in Ukraine is getting worse; cease-fire after cease-fire have collapsed. What is happening is very clear. Embelden by the easy takeover of Crimea, the Pro-Russian separatists supported by the tacit approval of president Putin of Russia are the cause of this crisis. He is playing a good game but he is not sincere and he wants the charades to continue. Russia wants to see East-Ukraine separate for many reasons; political, military, a buffer zone between East and West Ukraine and better access to Crimea. If he continues to meddle, it will go on forever and he knows that NATO will not intervene in this conflict as thousands would die foe no good reason or solution. After all, he took Crimea without firing a shot!
