The DR Congo army and M23 on Friday clashed near the main city in the country's volatile east as the UN warned the raging conflict had displaced over 400,000 people this year and could spark a regional war.
Since peace talks failed, M23 fighters backed by Rwandan troops have gained swathes of territory in east DRC in recent weeks, triggering a humanitarian crisis and ringing the provincial capital Goma, which is home to a million people.
