About 200 servicemen led by the Georgian Interior Minister crossed the border and entered Verkhny Karzman village with both Georgian and Ossetian population, chairperson of the South Ossetian information and press committee Irina Gagloyeva told RIA Novosti by phone.
"About 600 Georgian interior servicemen are deployed on the border with the Dzhavsky district near Sinagur and Karzman villages," she said.
"These are small villages and we are afraid that they will be destroyed," Ms Gagloyeva said.
The Georgian Interior Ministry denies information on its servicemen's invasion of South Ossetia.
"This is provocative and false information. The Georgian Interior Ministry did not deploy any units in the conflict area," spokesman for the Georgian Interior Ministry Guram Donadze told the Novosti-Georgia agency.
According to him, the situation in the conflict zone is stable at the moment.
Meanwhile, Tbilisi officials give contradictive information on whereabouts of Georgian Interior Minister Irakly Okruashvili, head of the coordination center in the Georgian-Ossetian conflict area.
"Mr. Okruashvili is in Tbilisi now," Guram Donadze said.
However, chairman of the parliamentary defense and security committee Givi Targamadze confirmed that Irakly Okruashvili was in the Tskhinvali region (the Georgian name of the self-proclaimed republic).
"Irakly Okruashvili is traveling over the Tskhinvali region. The minister's movements across his country concern nobody," Givi Tagramadze, currently in the conflict area, told RIA Novosti.
However, in his words, Mr. Okruashvili is accompanied only by his bodyguards.
Before his departure from Tbilisi to Baku U.S. ambassador Steven Mann will meet with Russian Foreign Ministry's ambassador at large Lev Mironov on Thursday.
The U.S. is concerned about the situation in South Ossetia, Mr. Mann told journalists following his meeting with Georgian Prime Minister Zurab Zhvania.
"U.S. Secretary of State Colin Powell wants to be sure that the U.S. is doing its best for the peaceful settlement of the Georgian-Ossetian conflict. That's why I am here," the U.S. ambassador said.
