A Mexican newspaper in the border city of Juarez announced Sunday that it's closing its doors due to security concerns for journalists.
Norte executive Oscar Cantu Murguia explained his decision to shut down in a letter that was published on the front page of the paper.
In that letter, Cantu cited the recent murder of journalist Miroslava Breach in the city of Chihuahua as a reason behind the decision. She was a reporter for the national paper La Jornada, but had previously collaborated with Norte.
"On this day, esteemed reader, I address you to report that I have made the decision to close this newspaper due to the fact that, among other things, there are neither the guarantees nor the security to exercise critical, counterbalance journalism," Cantu wrote.
Cantu added that he is not willing to have any more of his collaborators sacrifice their lives or die on his watch in the name of journalism.
Since 1992, at least 38 journalists have been killed in Mexico because of their work, according to the Committee to Protect Journalists. The same group said another 50 were killed during that time period, but it remains unclear whether those were because of their work.
"Mexico is clearly going through a deep, full-blown freedom of expression crisis," said Carlos Lauria, Americas director for the CPJ.
There were a series of attacks on journalists in March.
One journalist was gunned down as she left her home on March 23 and two others were killed in Guerrero and Veracruz.
