The government of Mexico's Gulf coast state of Tabasco is threatening legal action against people who spread rumors of drug violence on social networking sites.
Some of the tweets and Facebook posts cited by the government appear threatening. Other posts that warn people not to go out because there is a supposed "curfew" could fall under laws prohibiting threats.
But some of the cited posts appear to simply refer to gunfights that have killed people in the area recent days.
A state government statement Tuesday says authorities are tracing messages and will "act with all the weight of the law" against posters.
Tabasco officials refuse to specify what laws have purportedly been violated or what charges could be brought.
