Roki Tunnel
On 7 August 2008, the Georgian authorities received foreign intelligence reports about movement of Russian troops towards the Roki tunnel. Russian troops had illicitly crossed the Russo-Georgian state border and advanced into South Ossetia by 7 August, before the Georgian military response. According to "Der Spiegel", the Georgian tanks were to advance to the Roki Tunnel to seal it off. The Georgian aircraft's target was only the Gupta bridge, which links the northern part of South Ossetia to its southern part where Tskhinvali is located.
