MEXICO CITY (AP) - A newspaper in the northern Mexico border city of Nuevo Laredo says it will no longer cover violent criminal acts after the second of two grenade attacks against its office.
Other northern Mexican newspapers have quietly adopted such policies of not covering drug cartel violence.
But the announcement Tuesday by the newspaper El Manana was public.
El Manana said in a statement that what appeared to be a grenade detonated on the outside wall of its offices in the city across the border from Laredo, Texas.
The explosion caused no injuries.
Gunmen also threw grenades and opened fire Tuesday on two buildings belonging to the El Norte newspaper in the northern state of Nuevo Leon.
Drug cartels have threatened newspapers and killed reporters in northern Mexico.
