UNITED NATIONS – The UN envoy to Libya says the country's new leaders must act quickly to address major security challenges that have led to serious outbreaks of fighting and impose control over rival militias, tribes and armed backers of Moammar Gadhafi's ousted regime. Tarek Mitri told the UN Security Council Thursday that a year after Gaddafi's overthrow, Libya has moved forward in its political transformation. He pointed to parliament's approval on Oct. 31 of a new cabinet and progress “toward stabilizing a country bereft of democracy, institutions, human rights and rule of law over the last 42 years.” But Mitri said pressure is mounting on the new government from the Libyan people “to act decisively and quickly to build and reform” state security institutions including the military, police and judiciary. – AP
