Protesters guard the barricades

Protesters guard the barricades in front of riot police in Kiev, Ukraine, Monday, Jan. 27, 2014. Ukraine's justice minister is threatening to call for a state of emergency unless protesters leave her ministry building, which they occupied during the night. The seizure of the building early Monday underlined how anti-government demonstrators are increasingly willing to take dramatic action as they push for the president's resignation and other concessions. Protesters now occupy four sizable buildings in central Kiev, including the city hall. (AP Photo/Efrem Lukatsky)
