Russia: troops in South Ossetia to enforce peace

President Dmitry Medvedev says Russian troops sent into Georgia's breakaway province of South Ossetia must force Georgia into a cease fire. Medvedev says Russian forces also have a mission to protect civilians in South Ossetia. Many of the region's residents hold Russian passports. Medvedev made the statement Saturday at a meeting with his defense minister. Georgia launched a massive offensive to regain control over the breakaway province. Russia has close ties with the province and responded by sending in armed convoys.
