Ancient slingstones found in northeastern Spain may be evidence of a local uprising against Roman rule in the first century B.C.

Archaeologists think the lead sling "bullets" were fired by Roman soldiers after an ambush orchestrated by the local Indigenous Ceretani (also spelled Cerretani) people, who by this time had spent almost 200 years resisting Roman expansion in Iberia.
