UNO: In an effort to protect its two white helicopters delivering humanitarian aid in eastern Congo from militia attacks by standing out from other aircraft, the UN painted them bright orange. Since the M23 rebel group, one of many armed militias operating in the area, launched a new offensive last year, security has gotten worse in east Congo. The fighting has engulfed humanitarian efforts to aid the thousands of civilians who have been displaced by the fighting.
