This footage shows archeologists discovering two mass graves of Spanish Civil War victims in Belchite, Zaragosa, Spain on October 28.

One of the large cavities has already shown 15 bodies and could contain up to 150.

Promoted by the Mariano Castillo Association for the Recovery of the Democratic Memory of Belchite and financed by the central and Aragonese governments, the project is co-directed by the anthropologist José Ignacio Lorenzo, the archaeologists Gonzalo García, Sergio Ibarz and Hugo Chauton and the restorer Eva Sanmartín. They have the collaboration of volunteers and historians.

Belchite was one of the bloodiest battlefields during the Spanish Civil War, which took place between 1936 and 1939.

Officials say fifteen bodies have been found in one of the graves, and estimate that the remains of around 150 people could be buried there. A total of 400 people from Belchite and the surrounding area were killed in the town during the war following the 1936 coup, led by former dictator Francisco Franco.
