Russia accused Georgia of "aggression against South Ossetia", and launched a large-scale land, air and sea invasion of Georgia with the pretext of a "peace enforcement operation" on 8 August 2008. Russian airstrikes against targets within Georgia were also launched. Abkhaz forces opened a second front on 9 August by attacking the Kodori Gorge, held by Georgia. Tskhinvali was seized by the Russian military by 10 August. Russian forces occupied the Georgian cities of Zugdidi, Senaki, Poti, and Gori (the last one after the ceasefire agreement was negotiated). The Russian Black Sea Fleet blockaded the Georgian coast.
