Since the Libyan Civil War in 2011, relations between the two nations have worsened. In 2013 Chadian president Idriss Déby accused the new Libyan authorities of allowing Chadian mercenaries to establish camps in Libya from where they plotted attacks into northern Chad. Since the second Libyan civil war began between different factions in Libya, mercenaries from Chad and other countries in the region had been taking part in the conflict. In August 2016, the Libyan authorities closed their embassy in N'Djamena and recalled its ambassador, Mohammed Khalifa, at the decision of Chad. It came after the Chadian foreign ministry expelled 13 Libyan diplomats from Chad. According to a statement from the ministry, "We noticed that there are a huge number of administrative and military diplomats working in the embassy. Their stay in Chad is unjustified." Libya's internationally-recognized Government of National Accord noted concerns about over-staffing of Libya's embassies abroad. In January 2017, Chad had closed its northern border along Libya as the country's dissent into chaos would force some militant fighters to flee into Chad itself. As a result, Chad had ordered troop deployments at the border to make efforts to stop any militants fleeing into the country.
