(CNN) -- Unrest intensified over the weekend in Ukraine, further raising fears of a civil war or invasion by Russia. On Friday, 46 people died in clashes in the port city of Odessa. On Sunday, pro-Russian forces stormed the city's police station and secured the freedom of protesters who had been arrested as part of Friday's unrest. Here's a look at the situation on the ground in Ukraine and what might happen should the violence continue to escalate: Is Ukraine sliding toward civil war? It's a very real possibility, analysts say. Russia appears to be guiding the country in that direction by inciting unrest between pro-Russian interests and Ukrainian forces, said former U.S. diplomat Christopher Hill. By sowing the seeds of unrest, Russia can make it appear that the government in Kiev is incapable of governing. "So I think the Russians have a real interest in keeping this type of crisis going, hoping it can even go to a kind of civil war and basically justify whatever it is that they want to do," Hill said Sunday on CNN.
