The Tumeremo massacre occurred on 8 March 2016, in which 28 miners were murdered and kidnapped in the town of Tumeremo, located in the state of Bolívar, Venezuela. On the night of 4 March 2016, they were in the Atenas mine, on the border between the municipalities of Sifontes and Roscio, a poor area where, like most of the southeast of the country, the main economic activity is mining.
