rightfully so ukraine has been praised for its stiff resistance so far, but there is still a lot of force not in the fight from russia. a 3-mile long column of tanks and artillery is making its way and that could change the situation on the ground. >> it seems, in russia this isn't playing so well with the russian people. >> russian military finally admitted its first casualty without giving a specific figure, the ruble has taken a hard hit. about 40% of its value. if you had rebels in the bank there were about 40% less than they were before this crisis started. you can't use foreign credit cards, it's hard to fly, airlines shutting down and today could be a disaster for the ruble. >> what lies ahead, that's a good question.
