In March 2014 a coup d'état occurred in Ukraine, led by the ultranationalist organization Ukrainian National Revolutionary Front, which the recently formed government of Ukraine (in the aftermath of the Euromaidan). Following the ousting of President Viktor Yanukovych, many of the radical far right organizations that took part in taking over government buildings felt excluded from the new government. The new government demanded that these groups disarm in late February. In response, several of these far right groups (most notably Svoboda and Right Sector) unified into one political bloc, the Ukrainian National Revolutionary Front (UNRF). On 3 March 2014, they stormed government buildings in Kiev and arrested Arseniy Yatsenyuk, the interim Prime Minister of the new government.
