The document summarizes a referendum held in the Donetsk and Luhansk regions of Ukraine on May 11, 2014 regarding more autonomy or possible annexation by Russia. Putin had urged separatists to delay the referendum due to fears it could increase violence, while the U.S. rejected the referendum as illegal. The organizers said the vote was on more autonomy, but leaving open the possibility of independence or annexation by Russia. Results of the referendum were viewed cautiously due to similarities to events in Crimea.
