MOSCOW (Reuters) - Russian Foreign Minister Sergei Lavrov said on Wednesday that international efforts to reach a peace settlement in Libya should be intensified, the RIA news agency reported. Libya descended into chaos after the NATO-backed overthrow of leader Muammar Gaddafi in 2011. In October, the two major sides in the country’s war - the internationally recognized Government of National Accord (GNA) and Khalifa Haftar’s eastern-based Libyan National Army (LNA) - agreed a ceasefire.
