Mexico City, Apr 9 (IANS/EFE): The manager of the Facebook and Twitter accounts for Valor por Tamaulipas, or VxT, an outlet that reports on drug-related violence in the northeastern Mexican state, said he was shutting down the sites nearly two months after a drug cartel put a price on his head.

"I cannot remain in this trench for different reasons, I believe it is not necessary to explain them. And I do not know if you will believe that I have not surrendered and will not surrender. But I believe I have given all I can give and it has started to become impossible to manage the web site, the reports, the risks," the unidentified online journalist said in a Facebook post.

"The social networks are a battlefield on which the main users have some type of interest or role in this war," the message said.

Valor por Tamaulipas, whose name means "Courage for Tamaulipas", has 214,000 "likes" on Facebook.

The online media outlet has reported on drug-related violence in Tamaulipas, a state plagued by a turf war pitting the Gulf cartel against the Los Zetas and Sinaloa cartels.

A drug cartel put a bounty of $47,200 in February on the head of the manager of Valor por Tamaulipas's Twitter and Facebook accounts.

The outlet's posts are widely followed in northern Mexico.
