War in Abkhazia: A helicopter carrying evacuees was shot down during the siege of Tkvarcheli, resulting in at least 52 deaths and catalysing more concerted Russian military intervention on behalf of Abkhazia.

The War in Abkhazia was fought between Georgian government and paramilitary forces, and a coalition of Abkhaz separatist forces and North Caucasian militants between 1992 and 1993. Ethnic Georgians who lived in Abkhazia fought largely on the side of Georgian government forces. Ethnic Armenians, who formed the Bagramyan Battalion and Russians within Abkhazia's population largely supported the Abkhazians and many fought on their side. The separatists received support from thousands of North Caucasus and Cossack militants and from the Russian Federation military forces stationed in and near Abkhazia.

The Abkhazian town of Tkvarcheli was put under siege by the Georgian National Guard during the 1992–93 War in Abkhazia. The siege lasted from October 1992 to September 1993, almost the entire duration of the war, but was eventually unsuccessful. It was accompanied by inconclusive fighting in surrounding villages. Russian aid, both humanitarian and military, was critical for the defence of the town which suffered a severe humanitarian crisis during the siege.

Abkhazia, officially the Republic of Abkhazia, is a partially recognised state in the South Caucasus, on the eastern coast of the Black Sea, at the intersection of Eastern Europe and West Asia. It covers 8,665 square kilometres (3,346 sq mi) and has a population of around 245,000. Its capital and largest city is Sukhumi.
