Four people died and six were wounded late Sunday when an explosion rocked a cafe in Georgia's pro-Russian separatist province of Abkhazia, Interfax news agency reported Monday.
A local official quoted by the agency said "a local security official and a local resident" died on the spot while two other people including a translator working for a UN mission in Abkhazia succumbed to their wounds in hospital.
An inquiry was opened, he added.
The leader of the separatists in Abkhazia, Sergei Bagapsh, accused Tbilisi of having organised the "bombing" in the Gali region, declaring: "This attack confirms once again that Georgia has taken the road of state terrorism.".
