A union leader in the oil industry in the central Colombian province of Meta was gunned down by hired killers riding a motorcycle, officials said Saturday.

Edith Santos was hit with two bullets in the chest while in her office at San Isidro de Chichineme in Acacias, Meta Province, the USO petroleum workers union said in a communique.

The union leader's family took her to a medical center in the region where she soon died.

Santos was president of a community association and assessor for the National Security Professionals Union, or Sinproseg, which represents bodyguards and security guards in all Colombia.

USO laments this "attack on labor leaders in the oil industry," and recalled that Marcos Suarez, secretary general of the United Workers of Colombia, or CUT, was also murdered. EFE
