Georgian authorities say a mine explosion hit a police vehicle near the separatist region of South Ossetia killing one policeman and wounding four others.
Interior Ministry spokesman Shota Utiashvili says the blast occurred on Sunday morning near the village of Dvani.
South Ossetia was the flashpoint of the August war between Georgia and Russia. Georgian troops were driven out of South Ossetia, and another separatist province, Abkhazia.
Russia recognized both regions' independence and has placed large troop contingents there. Since then, sporadic violence has been reported in Georgian areas next to the provinces.
