For a second consecutive day March 19, presumed narco-gunmen blocked highways in the area of Mexico's northern industrial hub of Monterrey, seizing private automobiles, buses and ambulances from motorists and using them to clog the lanes. The Nuevo Leon state Public Security Secretary reported more than 30 roadblocks using more than 60 vehicles in the metropolitan area on the second day of the action, which they said was apparently aimed at halting army operations on the northern border. A shoot-out with army troops was reported in the suburban municipality of China. (Reuters, La Jornada, March 19)
