Mexico City - It started with small groups of students demonstrating against the Mexican Army. A few days later the protestors were 200-strong and growing increasingly aggressive.
Officials in Mexico claim that powerful drug cartels are paying protestors to block streets in protest and disrupt life in the northern Mexican city of Monterrey.
In exchange for demonstrating against the military presence, recruiters are apparently handing out school backpacks and 500 pesos (about 35 dollars) in cash per person, the Mexican daily Reforma reported.
