On 7 August 2008, Georgian president Mikheil Saakashvili announced a unilateral ceasefire and called for peace talks. However, escalating assaults against Georgian villages (located in the South Ossetian conflict zone) were soon matched with gunfire from Georgian troops, who then proceeded to move in the direction of the capital of the self-proclaimed Republic of South Ossetia (Tskhinvali) on the night of 8 August, reaching its centre in the morning of 8 August. According to Russian military expert Pavel Felgenhauer, the Ossetian provocation was aimed at triggering the Georgian response, which was needed as a pretext for premeditated Russian military invasion. According to Georgian intelligence, and several Russian media reports, parts of the regular (non-peacekeeping) Russian Army had already moved to South Ossetian territory through the Roki Tunnel before the Georgian military action.
