In the summer of 1977, Moroccan troops controlled again the town, this time for nearly two years. In March 1979, and after the Battle of Tifariti, the town was taken by the Polisario troops, the SPLA,  During the 1980s, the Moroccan Wall was constructed north of Tifariti, and the terrain around the town was heavily mined. The risk is greatest east of the Berm, especially in the areas of Mehaires, Tifariti and Bir Lahlou where the Royal Moroccan Army (RMA) conducted offensive operations in August–September 1991. The dangerous result is, among others, scattered cluster bombs, still active in these areas. In August 1991, weeks before the proclamation of the ceasefire, the Royal Moroccan Air Force repeatedly bombed Tifariti, destroying the buildings and the wells, as well as killing dozens of civilians. Hospitals and administrative buildings were built here between 1989 and 1991 by foreign aid agencies in preparation for a Sahrawi refugee return to Western Sahara, for the holding of a UN-backed referendum on either independence or integration with Morocco. That infrastructures were destroyed by the Royal Moroccan Air Force in August 1991, a few days before the proclamation of the cease-fire. A United Nations airstrip and a base for the MINURSO's peace keeping forces is situated close to Tifariti. In April 1999, the "Navarra Hospital" was inaugurated. It was built up with the collaboration of solidarity associations from that Spanish autonomous community. In January 2001, the patients and equipment of the hospital were evacuated, because of the threat of a restarting of the war. Finally, in February 2006, the hospital was re-opened. On May 21, 2005, and during the celebrations of the 32nd anniversary of the creation of the Polisario Front, Mohamed Abdelaziz (President of the SADR) put the first brick of the building that will host the Sahrawi Parliament, the Sahrawi National Council, and also the first brick of the ""Solidarity neighbourhood"" new district. On February 27, 2007 (31st anniversary of the proclamation of the Sahrawi Arab Democratic Republic) a borough of 150 houses named ""Solidarity neighbourhood"" was inaugurated by SADR's president, Mohamed Abdelaziz. It was built with the help of the Andalusian provinces of Sevilla and Málaga. On December 21, 2007, Abdelaziz inaugurated a mosque, in the framework of reconstruction and settlement of the Free Zone.
