The situation in South Ossetia is becoming increasingly worse, Georgian Prime Minister Zurab Zhvania told foreign ambassadors in Tbilisi on Thursday. \"Our post between the villages of Tamarasheni and Kurta in South Ossetia has been attacked,\" he said. \"We are closely watching the developments and doing our best to prevent an armed clash,\" he said. Zhvania said he would speak to Russian Security Council Secretary Igor Ivanov about the situation in South Ossetian by telephone immediately following his meeting with the ambassadors. South Ossetia has denied Zhvania\'s statement that Ossetian units allegedly attacked a Georgian post. \"This is sheer misinformation. Not a single Ossetian unit has conducted any operations in that area. The search for illegal Georgian units to expel them from the district is underway in a different area,\" head of the South Ossetian Information and Press Committee Irina Gagloyeva told Interfax by telephone on Thursday.
