More than a year ago, Libyan military commander Khalifa Haftar launched an offensive to seize the capital Tripoli from the UN-recognised unity government. The latest chapter in Libya's nearly decade-long conflict has since killed hundreds and displaced over 200,000. Here is a recap. On April 4, 2019, Haftar orders his troops to advance on Tripoli, seat since 2016 of the Government of National Accord (GNA), which he claims is backed by "terrorist" groups. Haftar supports a parallel administration based in the eastern city of Tobruk and his forces already control the country's main oil fields in the south. The assault comes as United Nations Secretary-General Antonio Guterres visits Libya in a bid to cement a political deal on holding elections. The next day, the Security Council calls on Haftar's forces to halt their advance. On April 7, Haftar's forces say they have carried out their first air strike on a suburb of Tripoli, where the GNA is based. The GNA announces it has launched a counteroffensive. On April 19, the White House says President Donald Trump recognised Haftar's "significant role in fighting terrorism and securing Libya's oil resources". In a blow to the ambitious commander's campaign, on June 26 GNA forces retake the town of Gharyan, the main supply base for Haftar's forces southwest of the capital. In late July, UN envoy Ghassan Salame proposes a three-point plan: a truce, a high-level meeting of concerned countries, and intra-Libyan talks. On November 5, 2019, The New York Times reports that Russia has sent mercenaries to support Haftar. Moscow denies the claim. On November 27, Turkey and the GNA sign a deal covering military cooperation and maritime boundaries, allowing Ankara to claim rights over areas coveted by other countries including Greece. A UN report on December 10 accuses several countries of breaching a 2011 arms embargo by supplying both camps. While Turkey and Qatar support the GNA, Haftar is backed by Egypt, the United Arab Emirates, Saudi Arabia and Jordan, among others. On January 5, 2020, Turkish President Recep Tayyip Erdogan announces the deployment of Turkish troops to Libya. Turkey and Russia broker a ceasefire that comes into effect on January 12. The next day in Moscow, GNA chief Fayez al-Sarraj signs the deal -- but Haftar leaves a day later without doing so. On January 18, forces allied with Haftar block oil exports from key Mediterranean terminals, paralysing Libya's main economic lifeline. The next day, at a summit in Berlin, world leaders commit to ending all foreign meddling and to upholding the 2011 weapons embargo. But on March 2, Salame announces his resignation, citing health reasons and saying he "tried to unite Libyans and restrain foreign interference". On April 13, pro-GNA forces capture two key cities on the coast west of Tripoli from Haftar's fighters. UN experts report on April 24 that 800 to 1,200 mercenaries from the Wagner Group, a Russian paramilitary organisation, are fighting in Libya in support of Haftar alongside Syrian fighters from Damascus. On May 18, the unity government says its forces have seized the strategic Al-Watiya air base, 140 kilometres (90 miles) southwest of Tripoli, which had been used by Haftar's forces to launch bombing raids. On May 23, the GNA forces say they seized three barracks from pro-Haftar fighters. Talks on a ceasefire resume on June 3, and on the same day, government forces retake Tripoli International Airport after heavy fighting. On June 4, the GNA says it is back in full control of the capital and its suburbs. acm/eab-jmy/lg/par
