Mexican authorities say gunmen have killed a federal prosecutor for the border state of Coahuila.
A federal official in Coahuila says Victor Manuel Martinez Cortez was about to leave his home in the City of Torreon when he was attacked Wednesday while sitting in his car.
The official spoke on condition of anonymity because of the ongoing investigation. He said Martinez had been working at the federal Attorney General's Office in Coahuila since 2005.
Authorities say the Zetas and the Sinaloa drug cartel are fighting to control smuggling routes in the state.
On Tuesday, gunmen set a fire at the office of the Torreon newspaper El Siglo and fired shots at it. No injuries were reported.
