Following the election of Vladimir Putin in Russia in 2000 and a pro-Western change of power in Georgia in 2003, relations between Russia and Georgia began to deteriorate, reaching a full diplomatic crisis by April 2008. From 1 August 2008, South Ossetian separatists shelled Georgian villages, with a sporadic response from Georgian troops in the area.[32][33][34][35][36] Artillery attacks by pro-Russian separatists broke the 1992 ceasefire agreement, which stipulated this type of weaponry was not allowed to be deployed in the conflict zone.[38][39][40] When Georgian president Saakashvili announced a unilateral ceasefire on the evening of 7 August 2008,[41][42][43] a new wave of South Ossetian attacks on Georgian villages followed.[44] This triggered the Georgian government into "restoring the constitutional order",[45] and sending the Georgian Army to the South Ossetian conflict zone just before midnight on 7 August.[46]
