The top U.N. envoy to Libya on Thursday warned that the escalation of violence in the capital can threaten the fledgling political process in the country. "The quick pace with which developments have unfolded in Tripoli over the past couple of weeks are a reflection of the deeply fractured political scene which continues to hang heavily over the country, undermining its fledging political process," Tarek Mitri, the head of the U.N. Support Mission in Libya (UNSMIL), told the security council via a video-link from Lebanon.
