In 1911, Italy went to war with the Ottoman Empire and invaded Ottoman Tripolitania. One of the most notorious incidents during this conflict was the October Tripoli massacre, wherein many civilian inhabitants of the Mechiya oasis were killed over a period of three days as retribution for the execution and mutilation of Italian captives taken in an ambush at nearby Sciara Sciat. In 1912, 10,000 Turkish and Arab troops were imprisoned in concentration camps in Libya, all Turkish troops were executed.
