(adds quote, UNHCR statement) GENEVA, Aug 14 (Reuters) - The International Committee of the Red Cross (ICRC) has received a green light from authorities to assist the civilian population in South Ossetia, but security concerns remain, an ICRC spokeswoman said on Thursday. "Russian, South Ossetian and Georgian authorities in principle are ready to give us access but we're being told there are ongoing security concerns," ICRC spokeswoman Anna Nelson told Reuters. "We won't be going in tonight because it is already dark. We hope to be able to go in as soon as possible," she said. The neutral humanitarian agency has been seeking to bring vital aid supplies into the rebel Georgian region, where it says tens of thousands of civilians require assistance and protection after a week-long conflict. But insecurity still reigns in parts of Georgia, including near the town of Gori, where the United Nations refugee agency said two of its staff were forced at gunpoint on Thursday by "people in unmarked uniforms" to leave their vehicles and hand over the keys. "The two later made it safely back to Tbilisi. Later authorities called from Gori to say they had recovered the vehicles," the U.N. High Commissioner for Refugees (UNHCR) said in a statement.
