UNITED NATIONS, Jan 30 (Reuters) - The United Nations is deeply concerned by credible reports that Rwandan-backed M23 rebels in eastern Democratic Republic of Congo are rapidly moving towards South Kivu's capital Bukavu, U.N. spokesperson Stephane Dujarric said.
The U.N. peacekeeping mission in Congo, known as MONUSCO, said there are also reports of Rwandan troops crossing the border "in that direction," Dujarric said.
