in the city in the summer of 2018. On 7 February 2019, the SDF media center announced the capture of 63 ISIL operatives in the city. According to the SDF, the operatives were a part of a sleeper cell and were all arrested within a 24-hour time span, ending the day-long curfew that was imposed on the city the day before. In mid-February 2019, a mass grave holding an estimated 3,500 bodies was discovered below a plot of farmland in the Al-Fukheikha agricultural suburb. It was the largest mass grave discovered post-ISIL rule thus far. The bodies were reported to be the victims of executions when ISIL ruled the city. In 2019 a project called the "Shelter Project" was launched by international organisations in coordination with the Raqqa Civil Council, providing funding to residents of partially destroyed buildings in order to aid with their reconstruction. In April 2019 the rehabilitation of the Old Raqqa Bridge over the Euphrates was finished. The bridge was originally built by British forces during World War II in 1942. The National Hospital in Raqqa was reopened after rehabilitation work in May 2019. As a consequence of the 2019 Turkish offensive into north-eastern Syria, the SDF called on the Syrian Arab Army to enter the areas under its rule, including in the area of Raqqa as part of a deal to prevent Turkish troops from capturing any more territory in northern Syria. Scanning for Syria project (2017–2018) The Raqqa Museum had numerous clay tablets with cuneiform writing and many other objects vanishing in the fog of war. A particular set of those tablets were excavated by archaeologists from Leiden at the Tell Sabi Abyad. The excavation team cast silicone rubber moulds of the tablets before the war to create cast copies for subsequent studies in the Netherlands. As the original tablets were looted, those moulds became the only evidence of parts of the 12th century BC in Northern Syria. Having a lifespan of roughly thirty years, the moulds proved not be a durable solution, hence the need for digitization to counter the loss of the originals. Therefore the Scanning for Syria (SfS) project was initiated by the Leiden University and Delft University of Technology under the auspices of the Leiden-Delft-Erasmus Centre for Global Heritage and Development. The project received a NWO–KIEM Creatieve Industrie grant to use of 3D acquisition and 3D printing technology to make high
