Ukraine struggles over official language decision

Police and protestors have clashed in Ukraine over a bill passed on Tuesday making Russian an official language in areas where people speak it.
Ukraine's president Viktor Yanukovich says he may call a snap parliamentary election if the crisis continues.
Though the bill's not on the statute books quite yet, there's still a fierce struggle taking place in Ukraine between its Russian-leaning past, and a modern sense of independent nationalism.
