phase it down. the phase out will happen in the next three years. after that it will be illegal to use for anything other than treating sick animals. many applaud the decision, others say the guidelines will not do enough to keep people safe. >> i'm concerned that there'll be no change. they can continue to misuse antibiotics as they have opinion. >> it's unclear how much it will cost farmers and consumers. >> the f.d.a. is requiring licensed vetterin air yans to supervise the use of antibiotics. >> protesters in kiev are standing their ground after an overnight sweep left dozens injured. the u.s. condemned the violence and is considering taking action in the form of sanctions. robin forest ear walker has more from kiev.

refugee camps. lebanese people feel proper camps would encourage refugees to stay, like the palestinian refugees. it is seen as a threat. >> metrologists say the worst is yet to come. more than 800,000 syrian fled. 80,000 will spend the rest of the winter in tents. well most of the country is not seeing much in terms of rain or snow, except for the great lakes. that brings heavy snow just to the east of the lake erie and ontario. up to 20 inches of snow in the next 48 hours is expected.
