Two workers at Mexican business daily El Financiero have gone missing in the central state of Zacatecas, the newspaper’s deputy general manager said.

“This incident pains all of us who work at El Financiero,” Rogelio Cardenas said on Twitter.

He added in another message that the two workers disappeared on the outskirts of the like-named state capital, located 600 kilometers (370 miles) northwest of Mexico City.

Sources with the daily consulted by Efe said state and federal authorities were investigating the case.
