Armenia handed back the Lachin district to Azerbaijan Tuesday as part of a peace deal that ended six weeks of fighting over the breakaway region of Nagorno-Karabakh. Here is a timeline of developments since the accord was agreed: On November 9 Russian President Vladimir Putin brokers a peace deal as Azerbaijani troops are at the point of overrunning the Armenian-populated region of Nagorno-Karabakh, which broke away from Baku after a conflict in the early 1990s. Forty-five days of heavy fighting that started on September 27 left several thousand dead, including more than 100 civilians. Azerbaijan claims Armenia has "capitulated". Angry Armenians storm government buildings in Yerevan as peace terms become known. Their leaders agree to return the Aghdam district to Azerbaijan by November 20, the Kalbajar district by November 15 and the Lachin district by December 1. Russian peacekeepers are to be sent to guard the strategic Lachin corridor linking the separatist region with Armenia proper. Another corridor to the south will link Azerbaijan with its Nakhchivan enclave on the border with Turkey and Iran. The following day Turkey -- which had been accused of sending Syrian fighters to aid its ally Baku -- hails Azerbaijan's "significant gains". The ceasefire agreement makes no mention of the future status of the remaining Armenian-populated areas of Nagorno-Karabakh. By the end of the week Russia deploys its first of some 2,000 peacekeepers. As protests in Armenia continue, an opposition leader is accused of plotting to kill the prime minister. Artur Vanetsyan, former head of the country's security services, is detained along with other senior opposition figures during protests which brand the prime minister a "traitor". Azerbaijan agrees to extend the deadline for Armenians to withdraw from the Kalbajar district to November 25. Armenians burn their homes in the Kalbajar region which was taken from Azerbaijan by Armenian separatists in the early 1990s. Fleeing Armenian refugees begin to set their houses and farm buildings alight in other districts. Others begin returning to the region from Armenia. Up to 90,000 people -- some 60 percent of the population -- fled during the fighting. Russia says that as of Monday it has helped more than 25,000 return. On November 16 Turkish President Recep Tayyip Erdogan asks his parliament to authorise sending soldiers to Azerbaijan to establish a "peacekeeping centre" with Russia. Ankara pushes for a larger role in maintaining the peace, prompting France to ask the Kremlin to clear up "ambiguities" over the ceasefire, particularly the role of Turkey and of foreign fighters. On November 20 Azeri troops enter Aghdam, the first of three districts to be handed back by Armenia. Five days later Azerbaijan enters the Kalbajar district, which is between Nagorno-Karabakh and Armenia. Its forces finally on December 1 enter Lachin, the district around the Russian-guarded corridor linking Armenia with Nagorno-Karabakh that was formerly overwhelming Azerbaijani. nrh-fg/mm/lc
