In April 2014, the civilian armed forces in Donetsk and Lugansk oblasts of Ukraine had a bloody conflict with the Ukrainian government forces, and the civilian armed forces subsequently announced the establishment of the "people's Republic of Donetsk" and "people's Republic of Lugansk". Through the mediation of the international community, the two parties to the conflict reached a ceasefire agreement in Minsk, the capital of Belarus, in September 2014 and February 2015 respectively. Since then, large-scale armed conflicts have been controlled, but small-scale exchanges of fire have occurred from time to time. On the 18th of this month, the civil armed forces in eastern Ukraine announced that due to the risk of Ukrainian military action, they would evacuate local residents to Russia on a large scale from now on.
